Okay so I already called my doc just waiting for her to call back, but wanted to see if this has happened to anyone else (this is my 4th baby and has never happened before) okay so my baby is 2months, I got my first period the week of thanksgiving, then again the first week of dec and now I just got it again, yes 3 times in less then a month , and it's not spotting it's my straight on period , I'm kinda freaking out but tryna convince myself that it's just my body tryna regulate itself again, ugh
