My very first symptom was cramps around the time I should have started my period, but no period. Since I was an infertility patient, I had a blood test the day I should have started my period, and it was positive <img src="i/expressions/face-icon-small-wink.gif" border="0"> . I'm afraid that's all I can think of-at the moment, I can only remember how deliriously happy I was-lol.
I think nausea started for me between 6 and 8 weeks (6, I think). Swollen, tender boobs were always a typical symptoms of pms for me, but yes, after a few weeks/months, that was definitely a symptom! <img src="i/expressions/face-icon-small-wink.gif" border="0">
Oh, and after a short while, I was unbelievably tired (I am a light sleeper, but I could fall asleep sitting up while the cleaning lady (I love my dh! <img src="i/expressions/face-icon-small-smile.gif" border="0"> ) was vacuuming and talking to me when I was pregnant-lol).
