It's like suddenly we get pregnant and our bodies just fall apart lol! I'm glad it's nothing serious :)
The on call OB Doc said it sounded like a muscle and that it doesn't sound related to my pregnancy. So I might go to the doc to be sure on Monday if it stays buggin me!! So many aches and pains in pregnancy. Lol. Man oh man!
It sounds like maybe you have pulled a muscle. I also have had side pain but it seems to be wear baby is kicking me. I'd ask your OB about it. The ligament pain from what I know it around the hips and vaginal area. It is possible that it's muscle stretching or organs being pushed by baby. I wish I could be more help. Try and rest and take it easy. Feel better!
