Yea I thought I was havin them but I called my doc and I was 19 weeks and he was liek "no, their not braxton hicks, u cant have them that soon''.. But I have that same book and it says u can pretty soon after that, ive also heard of people havin em b4.. . Come to find out my uterus was contracting, but that was because of my bladder infection and being dehydrated.. He said theres a difference between your uterus contracting and braxton hicks? Beats me! All I know, is it can contract, I felt it at 19 weeks. Didnt hurt, but was uncomfortable to me, it got tight, and I put my hand on my low stomach and could feel it hardening.* y, r u having them?
