I am 24 years old, and I have a 3 year old daughter, and I am with her father currently. I have frequent movement in uterus, at least it feels like there, but am not pregnant. I've taken numerous pregnancy tests, and all have come back negative. This has been occuring for over a year now. It isn't uncomfortable, but just happens frequently. I want to know if something is wrong, but not sure if this is a sign of that. Please help me.
