I've been feeling the same exact way since about 5 weeks, well the head rush since I got the BFP. The abs being sore for me is a mix of constipation and the baby. I remember last pregnancy I felt it at about 6 weeks and it lasted the entire pregnancy! But once the baby started moving, I didn't notice it as much.
I've been having the same symptoms, other than that, I don't really feel pregnant. I seem to cramp up if I'm sitting with my legs up, or at night when I'm trying to get comfortable. I'm 4w 3d.
I used to get the cramps in my stomach with my last pregnancy but I'm guess I probably wont get it much because that was 4 months ago. It's your uterus stretching and it usually doesnt last that long. Im 6w6d and I probably only had it once, last pregnancy I had it almost everytime I stood up.
I've had this happen so far a few times. I am 7 weeks but my fetal age is 6wk 2days (according to my first US yesterday). It seems to happen most if I move suddenly, and I end up with a sharp pain as if I just stretched too far.
Thanks ladies...makes me feel better that I'm not the only one! :)
that's interesting, and though I've never experienced that, I see you're not alone! :)
