I am taking Yasmin birth control pills and took them regularly and on time. For some reason, I took the last one Friday night, and forgot until Tuesday night. I had sex on Saturday night and am now worried about pregnancy. How worried should I be? Also, in my panic I took 4 of the pill on Tuesday when I remembered and am worried about the effects of that. The leaflet that came with the pills said they contain potassium. Granted it was a silly thing to do, but should I be concerned now?
