Patient: I am on birth control (generic yaz) and had sex during the placebo week. We used a condom and I got my period on time two days later. I didn’t miss the period after either. I am however feeling out of sorts lately, light headed, stomach aches and frequent urge to pee. Could i be pregnant or are my symptoms unrelated? I take my pill daily, in the evening try to do it at the same time every day but tend to be off by a few hours each time. the pill pack i used before intercourse i know i had missed a pill once or twice but always took it when i remembered.
