My sis is 4 weeks pregnant and just found out and she was due for her perid today and she has been having craming is this normal or signs of mc??

Any signs of cramping should be told to your doctor. While it can be normal, at this early, I wouldn't take the chance. She needs to call her doc and have them see her.

Thank u so much is said it feels like a menstral cramping and I told her to get in to see the doc asap and she is calling now
