that's interesting, and though I've never experienced that, I see you're not alone! :)
Thanks ladies...makes me feel better that I'm not the only one! :)
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.
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 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'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.
