I'm 18wks 2days and all day off and on i've had this crampy sore feeling in my hip joints in the front. It lasts for a few seconds and then stops. This is my 3rd baby but don't remember it with my other 2. Tmi but i went to pee amd i had some discharge that had 2 blood dots in it and thats it. Nothing else. Anyone else had this before?
