I am 30 years old. Had a miscarriage last year in January at 8 weeks. I have always had a normal period, between 28-31 day cycle. My last period began on February 15 and so far (it is March 20) my period has not started. I have had cramps and increased cm but no pregnancy symptoms at all. I know after being pregnancy last year that by now I would have had a positive test but after taking several hpt’s including digital ones, they were all negative. Missing a period has NEVER happened to me before.

How many weeks should I wait before I go to a doctor??
