Not me. I’ve only been pregnant once. We had been trying for a few months, and one day I realized, “Hey, wait a minute. I’m late.” The rest (an 8th-grader now) is history.
I have never been pregnant.
The first time, SiL didn’t believe she was pregnant even after repeated sticks said she was. She had the notion (sadly very common) that “the average value given by statistics is the only possible value” - she wouldn’t have been able to phrase it like that, but it’s how she treated it. Since “the average time for a couple to conceive is two years,” she could not have gotten a hole in one. The hole in one is now three years old.
The second time, she was preparing breakfast, went 
and told my brother “oh my God, I think I’m pregnant!” A few days later the stick said yes; the baby is two months old.
My one and only - I looked in the mirror and said “You’re pregnant.” then laughed it off. Several days later I found myself arguing that although I really *needed that banana flavoured milk, I hate it so I reached for my favourite Chocolate milk instead - except I knew I’d barf if I drank that so I compromised with me and settled for strawberry, which I’m not really fond of.
It was another week or so that I realised my ‘regular as clockwork’ period was three days late. Like Cat=^…^=, I’d probably felt the hormone change triggered by implantation. I just talked myself out of it for another week and a half.
*It was pretty much all I could drink while I was preggers. I hate the stuff with the heat of a thousand suns now.
I knew just a week after conception. I’m a pretty heavy smoker, and I couldn’t smoke at all. It made me sick. I couldn’t even be around smoke. Also, my boobs hurt and I had no appetite. When my appetite came back, all the baby wanted was spicy food and chocolate. That’s my son, and at six years old, he still only wants spicy food and chocolate. I knew pretty much right away with my daughter, too. My boobs hurt again, and I peed a lot, but this time, I couldn’t eat anything spicy for nine months. She’s five now and doesn’t like spicy food.
With pleasure. She’s the littlestbug.
My husband was the one with all the woman’s intuition. We tried for only two cycles before succeeding. The first one I was sure I was pregnant and wasn’t, and he was sure I wasn’t. The second time I was absolutely certain I wasn’t, and he insisted that I was. He was right once again.
I was right on one thing, though–I KNEW she was a girl, right away. Never had a single boy dream, except for the one where I was pregnant with a rabbit. The rabbit was a boy.
With all three, my first symptom was irrational PMS-style rage, a full week before my period was due (and a week or so after conception). The first was completely and totally unexpected, but when I realized I was having PMS a week before my period, I had a feeling something was up.
With my first, I had just gone through some major life changes (marriage, overseas move) and thought that was at the root of the mood swings, the fatigue, the aversions to coffee and wine and mushrooms … I found out I was pregnant in my 13th week, and wasn’t he a lively little thing on the ultrasound screen!
With my second, I was aware I was pregnant before I missed my period. My sense of smell abruptly sharpened, and there was a noticable change to my lady bits. (ahem)
A friend of mine was pregnant for several months before she knew it. I’m still not clear on how that happened, exactly (her child is almost two now), but it’s rather a delicate subject, you know?
I knew immediately (OK, the day after conception).
And no, I’m not a woo-woo “I can-just-feel-it-psychically” type.
I was always very “in tune” with my body, was aware of my cycle and ovulation times. (TMI? ->) Around the time of ovulation, you can usually feel a little more . . . slippery . . . with a specific slightly clear, stretchy discharge.
I realized my cycle had been thrown off when I had strep throat the previous month, and that I had just ovulated, dammit (obviously unexpectedly)!
I waited the prerequisite time and took a home pregnancy test (negative), then another a week later (still negative), but all along I KNEW I was pregnant!
I also KNEW I was having a boy. OK, I was wrong on that one.
(She’s now a sophomore in college!)
The lady and I watched a show the other day called I Didn’t Know I Was Pregnant, featuring stories of women who gave birth without having known that they were pregnant up until the birth. They were not as overweight as you might imagine, and one of them gave birth to twins. The show was hilarious in its cheapness.
Be careful out there.
My SIL said she knew immediately that something was somehow “different.” She took a test, but it said no. “Too soon,” she thought and waited a couple of weeks. Still “no.” So she waited till she missed her period–STILL negative! She never doubted for a second that the tests were wrong, and finally went to get a blood test, which told her what she knew all along–she was indeed pregnant.
When she was eight month along, just for shits and giggles, she took another home PG test. It came up negative!
The next time, she never realized (until I suggested to her that her frequent trips to the bathroom might not be a UTI, since she wasn’t having pain) that she might pregnant again. It wasn’t long until she asked if she could use my son’s recently vacated crib! (I told her sure, no problem. A couple of weeks later, I had to renege–I found out that I’d be needing it myself in about seven months!)
I didn’t know immediately, but I remember coming home from work one day, exhausted for no reason and thinking to myself, “either I have the flu, or I’m pregnant.” I was pregnant.
I had one of those. She’ll be four in February. And I can’t explain it any better. We had indeed discussed trying to conceive, and I charted my fertility for a while, and then we decided we might as well try for a girl by having sex just outside my supposed fertile time - figuring we’d have plenty of times to try later. So we had sex 6 days before ovulation, and I new before we were done that was it. I had absolutely no doubt after that, ever, even though the method of birth control that I believe in utterly said I probably couldn’t be pregnant. Didn’t matter, I knew I was. About 7 weeks later, I took a pregnancy test just because my husband needed visual proof.
Also “just knew” with my son, and that was not at all planned or even welcomed.
“Just knew” one other time, but my period ended up coming six weeks “late” and very heavy, so I suspect that was an early miscarriage, but I never took a pregnancy test with that one.
Never had a serious scare otherwise. Even when my period has been late, never had a sense that I was pregnant when I wasn’t.
