I have irregular periods and have for years, but the most I've ever skipped was a period every other month. Anyhow, I've been having unprotected sex with my husband for the last 3 years (we've only been really trying the last year to conceive). In January 2009 I stoped taking the pill. Now, over the last 3.5 months I have not gotten my period (since Sept. 25, 2009). I've been extremely hungry and 3 hours after I eat I'm hungry again with a growling stomach, I am extremely tired, I have a constant pain in my lower back, there has been clear discharge, my jeans are getting tighter, I've been extra horny and I have pain in my side near the ribcage/midstomach area (it comes and goes). I've also taken 2 HPT's and they've come back negative. If anyone has any ideas about what's going on that would be very helpful!
