I've been on Microgestin Fe 1/20 for 7 months and I got my new pack Thursday and my boyfriend and I had sex on Friday and he came in me for the first time.. I always take my pill and at the same time and I took it the same time the next day after he came in me. But yesterday and today I was off by like 40 minutes taking my pill and I just experienced some very light bleeding when I went to the bathroom. Is that just because I took my at a different time for 2 days? And I'm not pregnant right??
