I usually take my pill at the same time and I got down to the placebo pills and I didn't take the last 3 placebo pills. I am a Sunday starter, and I had sex on Saturday, the last day for my placebo pills. I also had sex again on Sunday and forgot to take the first active pill to a new pack. I took my missed pill on the following Monday but not until later on through the afternoon, and my regular pill at the usual time. Is there a chance I could be pregnant?
