Okay so, last weekend I had sex on Saturday without a condom but he pulled out before ejaculation and then on Wednesday I was about 12 hours late taking my pill. Now this weekend I had sex on Friday again using the pull out method and then forgot to take the pill Saturday morning. I got my period about halfway through the day, took my pill about 12 hours later than I was supposed to and my period was gone in the morning when I woke up. I proceeded to take the active pills at the correct time. Could that one day have been implantation bleeding or did me taking the pill stop my period?
