Getting REALLY strong pains when I lay down. Doesn't matter if it's on my side or back. From my back to my belly. I have to sit up or stand to feel okay. Thought I was getting contractions but maybe they weren't haven't had one in the past 15 min or so. I did have some light spotting this morning. Idk
