with our first we weren't trying and I remember we were unprotected once because I miscounted days. this was not a subliminal thing at all. I just remember counting days and just feeling the color drain from my face, my body really. I think part of me had an inkling right then and there. thankfully normal pms symptoms eventually ensued...but then nothing. I tested when I was a couple of days late (never am late) and imagine my shock when a big fat positive showed in just a few seconds. shocked but not shocked if you know what I mean.
with our second (and third) we were starting to try, and realizing how quickly we got pg with our first we were pretty sure it wouldn't take long, in spite of my age (36). yep, pg a month and a half later (I had one weird month where my cycle was only 17 days...very strange. I was pg right after that). I knew I was pg then, just knew it. I had heartburn 4 days before I was due to start my period...I have only ever had heartburn when I was pg. I knew more what to expect this time around.
the big surprise was that it was twins, but not sure how much of a surprise that was for me honestly. I joined an on-line expecting club and started getting to know everyone. suddenly a few of the expectant moms were finding out, surprise, its twins. total shock to them, no drugs, no family history in a couple of cases, just SURPRISE. It got me thinking...I put a lot of weight on in the first trimester (11 pounds!), I was showing very very early. I tried to believe it was second baby syndrom, but in the back of my head I had a feeling something else might be up. we went for our first u/s at 15w6d and as I lay on the table while the tech prepped my belly for it I think there was a small part of me that was waiting for her to say, SURPRISE. When she did say it it felt like a shock and a confirmation all at once. I don't know how else to describe it.
good luck to you!!!
