actually Most people on here should be talking to their doctor first bc things could be more serious then you think. It could be the beginning of a placenta abruption. So don't be so rude when you ask someone for advice!
Last option is speaking to a Dr. For anyone. That shouldnt be anyones help or suggestion in this community. If u hav any idea on the subject then there should be an answer on what probably this signs indicate..
I don't think it's anything to worry about but if your concerned I would call the Dr just to be sure it can't hurt and that's what they are there for. Best of luck!!
