Hi everyone.... First time posting...

So for about a week to two weeks now I've been having cramping as if I'm supposed to get my period.... But AF hasn't shown up... The cramps are on and off and for the past 2 days it's almost continuously.

I stopped taking my BC in October and AF came every month... It was all normal except for last month. I was 45 days late and every test that I took said negative... I went to my doctor and she said it was a normal period. (I scheduled an appointment and the day before my appointment AF showed up) my last period was in May from 2-6th and I have yet to have it again this month... Is this something to be concerned about?
