Hello everyone. I had sex with my now ex boyfriend at the beginning of May and he didn't put on a condom at first but later on did use one and ejaculated inside the condom. We broke up the next day so I decided to take Plan B just to be on the safe side. I am not on any other birth control and got my period about a week later. My period in June was ten days early and normal length, then my period in July was about two weeks late and I am currently 18 days late for my period that I should have gotten in august. Part of me thinks I cannot be pregnant since I've gotten three period since this happened but I am still worried since I am still so late. Also, I haven't had sex since then either. If anyone can reassure me that this is normal or not would help a whole lot! Thanks everyone. Best wishes
