My boyfriend and I used a condum the first time we had sex. Im extremely paranoid about getting pregnant, so I asked him if me noticed any rips or tears after we had finished although it seemed as if we had used it correctly. He told me that to his knowlege there were none. I also had him purchase the Next Choice Emergency Contraceptive for me, which I took about 40 hours after we had sex and followed through with the second pill 12 hours later. I'm three days late starting my menstrual cycle, as it has been 26 days since I last got it. Is there a chance that I could still be pregnant? Or is the pill what's interfering with my cycle?
