hi yes it can happen if your late now's the time to do either an hpt or do a test at your doctors. but this could something to do with the hormones from bc doing this or it could be just a skipped period getting one of these can throw women at times if you have never had one. if you can think back just how many times before sex on the 25/6 did you have unprotected sex then? if you can work it out from the first day of you last period see sex 4 days before day 14 could have done it that was unprotected. hope something here helps. good luck
