I'm 22 weeks and have been experiencing cramps in the last 2 days. I've always had occasional cramps every week since the beginning (first trimester cramps were quite noticeable) and attributed it to baby growing and ligaments stretching, but these cramps feel a little stronger again. Are these Braxton hicks? How would I be able to tell??
