Thats what i did and i became pregnant im 6 weeks now:) i took first responce it tells u 6 days before your missed period
yea you could...sperm can live up to like 4-5 days or something...so if you had sex 3-4 days before ovulating you deffinatly could be. unfortunatly you can take a test for a couple weeks..be calm..i suppose your not wanting a baby right now, right? since you took the plan b?
Yup you could . If you don't want to get pregnant you should get on birth control and use backup protection. Good luck
