Pregnancy Info HOME

I have been on birth control (Ortho Lo, NuvaRing, and most recently Seasonique) for about 10 years. This is my first month off birth control. If you go by the "28 day cycle" theory, I should have started my period 7 days ago. I have had cramps on and off for about 4 days, and the worst bloating of my life. The only kicker is I would be approximately 27 weeks pregnant if I were indeed pregnant. I have not had any other signs of pregnancy. I was on Seasonique (the birth control where you have a period once every 3 months) for 6 months so I had two normal periods. At what point should I consult my OBGYN about a late period? I'm starting to get quite concerned that something just isn't right. Thank You.
