I got the GBS test at 37 weeks and my doctor doesn't do cervical checks until you're in labor unless there is a reason for concern or you ask her to. So I got my first cervical check 42 weeks with my first (long story there), 41 weeks with my second, and at 39 weeks 3 days with number three. he was born at 39 weeks 4 days.
My OB's office does the swab and first cervical check at your 36 week appointment!
i've felt like that since about 35 weeks also. I feel like my butt is clamped closed. Lol. Anyway, 39 weeks now and I'm not even dilated so her being low might not mean anything like me.
If it is painful ask to be checked.....I'm 28 weeks and I feel like my son is going to fall out my butt hole and my va jay jay hurts like hell. They checked yesterday just to make sure my cervix was still closed. I mean they get paid to make sure you're fine so just let them know.
