So I was on the marina IUD for two years and I just got it taken out on the 24th of April. The day I got it taken out I started taking the pill (Yaz). I didn't wait seven days to have sex nor did I have protected sex with a condom within those days. I have been feeling very moody and tired lately and have been eating more than I usually do and have been having food cravings. I have also been bloated. I am in the placebo part of my pill pack and my period was supposed to start two days ago and hasn't. When I had my IUD I didn't have a period, but with the pill the doctor said it was supposed to regulate my periods. So I haven't started my period yet and it makes me nervous. I took a pregnancy test today and it came up negative, but the fact that I haven't started my period yet and I only have two days left of the placebo pills I was wondering what I should do. Is there a possibility that I could be pregnant? Or is it the pills and the fact my body is getting used to the pills and getting used to the IUD not being there anymore?
