I am 14 weeks pregnant ad I also am a full time student. My campus is a big university and I have to walk long stretches from classes to car. A bit ago I was leaving a class and started feeling a really sharp feeling on my side. It lasted for maybe a minute. I stopped for a few seconds and sit and then it went away, I got home and when I went to the bathroom there was no blood or anything and I haven't had pain since. So is this probably round ligament pain, just because I walked a lot, or should I be worried?
