I had a laparoscopy done Jan 14 my last period was Jan 6, I was late ovulating I believe I ovulated Jan 20 but didn't have a way to test to see if opk was positive. But anyway I had one app tell me my period would start Feb 1 and one Feb 4. Last night I had some cramps and aching hips etc thought for sure I would start in middle of night but nope! I've been having cramps on and off since Thursday along with alots of cm... And negative test.. I do not know what to do?
