I am using Marvelon 28 for 2 Years now. We were very busy with our new apartment and it sucks that I forgot to take the first pill of my third week. I remembered it the next day, so what i did is to take the missed tablet and then take the tablet for that day. That was the instruction on their website, but because I want to make sure that I won't get pregnant because of the missed pill, I decided to take the placebo pills the following days. Thinking that i can still have my period for this month. As of now, I already consumed my third placebo pill but i still haven't got my period. Is there a chance that I am pregnant?
