Round ligament pain.... absolutely horrible, especially if you were in shape/toned before pregnancy. Happens in the "v" area usually, the ligaments detach and it is not pleasant but completely normal.
I'm having the same pain it comes up strong and sharp at times it's very uncomfortable. I'm 33 weeks pregnant and my baby is down in position I just think it's his weight putting extreme pressure and it's our ligaments and uterus stretching I'm sure but it wakes me up at night like lastnight and this early morning.
