Hi, everybody. My cycle has gotten really arre, and I wanted to see if anyone has had any similar experiences. I just moved back to the States after a year living in France. My cycle had finally become regular and predictable during the last three months of my stay. I went off the pill when I went abroad (to see if it was responsible for sudden weight gain) and didn't miss any periods. Since being back, I haven't gotten my period once! That's two and a half months overdue. I took two pregnancy tests. They were negative. I had sex right when I got back, on the last day of my period, with a condom. I just don't get what's going on with my system. Could change in environment really make this big of an upset or is it something more?
