When I breathe in really deep I usually get this sudden pulling sensation in my abdomen. It’s seems to happen very quick and it’s over with right away. There’s no pain involved, but it’s grabs my attention instantly is is sort of uncomfortable. I thought maybe it was a strong baby kick but there’s no way this early and it seems to happen when breathing in deep only. I know it can’t be round ligament pain because I have definitely felt that before and it usually comes on from sudden movements or twisting and turning. That is sharp pain that lasts up to 10 seconds for me. Any ideas? Similar experiences. The only other thing to add is that I have an anterior placenta. I’m currently 18 weeks pregnant. Help!
