Thread: Not sure what's going on

Hello everyone, here's my situation:

I have been on the same bc pill for a about 2 years now (Norynil-before that I was on a monthly shot). Last month I went to the pharmacy to pick up my refill (the same day I was to start taking it) and the pharmacist advised me that there were none available, and the only way for me to get something else required a prescription from my doctor. This was a Saturday and my doc is out of office on the weekends. I didn't get a prescription for another pill (Gynera) until Tuesday (so i was "pill-less" for 3 days). I decided to take 2 pills and continue the pack as usual (my doc said it was cool). Now here I am to this confusion...last Saturday would have marked the first day of my seven day break to get my period. It is day five and I have received nothing but light spotting just once today. I did have unprotected sex with my boyfriend and so I'm not certain if this is a sign of pregnancy or just a side effect of switching to this pill. Your advice is appreciated! Thanks
