So usually when I sleep at night I alternate between my right side and my left side. Last night when I'd lay on my right side my baby would go crazy and I don't know if he had less space or was uncomfortable or what but I just get this feeling that he didn't like it. So I slept on my left side all last night and when I would get up in the middle of the night to pee, my hips would like give out on me and I could barely walk. I made 3 trips to the bathroom last night crawling. I tried again to lay on my right side and baby boy would start flipping out so I went back to my left. Now that the night is over and I'm up for the day my legs and hips feel no better. I can barely walk without feeling that my hips/legs are gonna give out on me. I don't know what to do. 30 weeks😥
