So me and my ex from a 5 year relationship had sex on the 19th.. i ejaculated inside her. But she took plan B next morning. About 4 days later we had sex again and i am sure i ejaculated a bit inside her. She dint want to take plan B again. She said its not healthy. About a week later she said she got her period.. which was not due till sept 12  my a question and concern is can she still be pregnant even though she got her period or she should be fine?..
