I seriously think I am pregnant. How could we have been so stupid? Daniel and I were so carried away with euphoria at being back together again that reality seemed to go out of the window – and once you've . . . oh look, I don't want to talk about it. This morning I definitely felt the beginnings of morning sickness, but that could be because I was so hungover after Daniel finally left yesterday that I ate the following things to try to make myself feel better:

2 packets Emmenthal cheese slices.

1 litre freshly squeezed orange juice.

1 cold jacket potato.

2 pieces unbaked lemon cheesecake (very light; also possibly eating for two).

1 Milky Way (125 calories only. Body's enthusiastic response to cheesecake suggested baby needed sugar).

1 chocolate Viennoise dessert thing with cream on top (greedy baby incredibly demanding)

Steamed broccoli (attempt to nourish baby and stop it growing up spoilt).

4 cold Frankfurter sausages, (only available tin in cupboard too exhausted by pregnancy to go out to shop again).

Oh dear. Am starting to get carried away with idea of self as Calvin Klein-style mother figure, poss. wearing crop-top or throwing baby in the air, laughing fulfilledly in advert for designer gas cooker, feel-good movie or similar.

In the office today Perpetua was at her most obnoxious, spending 45 minutes on the phone to Desdemona, discussing whether yellow walls would look nice with pink-and-grey ruched blinds or whether she and Hugo should go for Blood Red with a floral freize. For one 15-minute interlude she said nothing whatsoever except, 'Absolutely . . . no, absolutely . . . absolutely,' then concluded, 'But of course, in a sense, one could make exactly the same argument for the red.'

Instead of wanting to staple things to her head, I merely smiled in a beatific sort of way, thinking how soon all these things were to be immaterial to me, alongside caring for another tiny human being. Next I discovered a whole new world of Daniel fantasies: Daniel carrying the baby in a sling, Daniel rushing home from work, thrilled to find the two of us pink and glowing in the bath, and, in years to come, being incredibly impressive at parent/teacher evenings.

But then Daniel appeared. I have never seen him look worse, The only possible explanation was that on leaving me yesterday he had carried on drinking. He looked over at me, briefly, with the expression of an axe-murderer. Suddenly the fantasies were replaced by images from the film Barfly , where the couple spent the whole time blind drunk, screaming and throwing bottles at each other, or Harry Enfield's The Slobs with Daniel yelling, 'Bridge. The baby Is bawlin'. Its 'ead off.'

And me retorting, 'Daniel. I am avin' ay fag.

Help. Monday and most of Tuesday I sort of thought I was pregnant, but knew I wasn't really – rather like when you're walking home late at night, and think someone is following you, but know they're not really. But then they suddenly grab you round the neck and now I'm two days late. Daniel ignored me all day Monday then caught me at 6 p.m. and said, 'Listen, I'm goin to be in Manchester till the end of the week. I'll see you Saturday night, OK?' He hasn't called. Am single mother.

Went to the chemist to discreetly buy a pregnancy test, I was just shoving the packet at the girl on the till, with my head down, wishing I'd thought to put my ring on my wedding finger, when the chemist yelled, 'You want a pregnancy test?'

'Shh,' I hissed, looking over my shoulder.

'How late's your period?' he bellowed. 'You'd be better with the blue one. It tells you if you're pregnant on the first day after your period is due.'

I grabbed the proffered blue one, handed over the eight pounds sodding ninety-five and scuttled out.

For the first two hours this morning I kept staring at my handbag as if it was an unexploded bomb. At 11.30 I could stand it no longer, grabbed the handbag, got in the lift and went to the loo two floors down to avoid the risk of anyone I knew hearing suspicious rustling. For some reason, the whole business suddenly made me furious with Daniel. It was his responsibility too and he wasn't having to spend ?8.95 and hide in the toilets trying to wee on a stick. I unwrapped the packet in a fury, shoving the box and everything in the bin and getting on with it, then put the stick upside down on the back of the loo without looking at it. Three minutes, There was no way I was going to watch my fate being sealed by a slowly-forming thin blue line. Somehow I got through those hundred and eighty seconds – my last hundred and eighty seconds of freedom – picked up the stick and nearly screamed. There in the little window was a thin blue line, bold as brass. Aargh! Aargh!

After 45 minutes of staring blankly at the computer trying to pretend Perpetua was a Mexican cheeseplant whenever she asked me what was the matter, I bolted and went out to a phone booth to ring Sharon. Bloody Perpetua. If Perpetua had a pregnancy scare she's got so much English establishment behind her she'd be down the aisle in an Amanda Wakeley wedding dress in ten minutes flat. Outside, there was so much traffic noise I couldn't make Sharon understand.

'What? Bridget? I can't hear. Are you in trouble with the police?'

'No,' I snuffled. "Me blue line in the pregnancy test.'

'Jesus. I'll meet you in Cafe Rouge in fifteen minutes.'

Although it was only 12.45 1 thought a vodka and orange wouldn't do any harm since it was a genuine emergency, but then I remembered that baby wasn't supposed to have vodka. I waited, feeling like a weird sort of hermaphrodite or Push-me-pull-you experiencing the most violently opposed baby sentiments of a man and a woman both at the same time. On the one hand I was all nesty and gooey about Daniel, smug about being a real woman – so irrepressiblv fecund! – and imagining fluffy pink baby skin, a tiny creature to love, and darling little Ralph Lauren baby outfits. On the other I was thinking, oh my God, life is over, Daniel is a mad alcoholic and will kin me then chuck me when he finds out. No more nights out with the girls, shopping, flirting, sex, bottles of wine and fags. Instead I am going to turn into a hideous grow-bag-cum-milk-dispensing-machine which no one will fancy and which will not fit into any of my trousers, particularly my brand new acid-green Agnes B jeans. This confusion, I guess, is the price I must pay for becoming a modern woman instead of following the course nature intended by marrying Abnor Rimmington off the Northampton bus when I was eighteen.

When Sharon arrived I sulkily thrust the pregnancy test with its tell-tale blue line, at her under the table.

'Is this it?' she said.

'Of course it's it,' I muttered. 'What do you think it is? A portable phone?'

'You,' she said, 'are a ridiculous human being. Didn't you read the instructions? There are supposed to be two lines. This line is just to show the test is working. One line means you're not pregnant – you ninny.'

Got home to an answerphone message from my mother saying, 'Darling, call me immediately. My nerves are shot to ribbons.'

Her nerves are shot to ribbons!

Spent the morning mooning abut in mourning for lost baby but cheered up a bit when Tom called to suggest a lunchtime Bloody Mary to get the weekend off to a healthy start. Got home to find a petulant message from Mother saying she's gone to a health farm and will call me later. I wonder what's the matter. Probably overwhelmed by too many Tiffany's boxes from love-sick suitors and TV presenter job offers from rival production companies.

11.45 p.m. Daniel just called from Manchester.

'Had a good week?' he said.

'Super, thanks,' I said brightly. Super, thanks. Huh! I read somewhere that the best gift a woman can bring to a main is tranquillity, so I could hardly, as soon as we've started properly going out, admit that the minute his back was turned I started having neurotic hysterics over a phantom pregnancy.

Oh well. Who cares. We're seeing each other tomorrow night. Hurray! Laialala.

Awake on VE Day in unseasonable heatwave trying to whip up frenzy of emotion in self about end of war, freedom of Europe, marvellous, marvellous, etc. etc. Feel extremely miserable about whole business, to tell truth. In fact, 'left out' might be the expression I am groping towards. I do not have any grandpas. Dad has got all worked up about a party being hosted in the Alconburys' garden at which, for unexplained reasons, he will be tossing pancakes. Mum is going back to the street she was brought up in in Cheltenham for a whale-meat fritter party, probably with Julio. (Thank God she didn't run off with a German.)

None of my friends are organizing anything. It would seem embarrassingly enthusiastic and all wrong, somehow, suggesting a positive approach to life or that we were trying creepily to annex something that was nothing to do with us. I mean, I probably wasn't even an egg when the war ended. I was just nothing: while they were all fighting and making jam out of carrots or whatever they did.
