I have always had a reggular menstral cycle even before I started birth control pills. I have reccently stopped since my husnband and i are trying to have a baby. November would have been my 5th month on a regulare cycle w/out the pills. I had my period for one day and thats it. I read it could be a sign of pregnancy so i took a test, but it was negative, but my sister in-law had to take it 3 times then it was positive and never got her peiod. So i was woundering what u think i shoud do..?
