I had sex for the first time today(unprotected) my period ended 2 days ago. he pulled out. calender says ovulating in 10 days also bloody mucus after?

Still unsafe: If u truly aren't ovulating for 10 more days u r unlikely to get pregnant but u can ovulate earlier than the calendar says & can get pregnant anytime u have unprotected sex.I have even delivered a baby for a girl who had not yet had her first period!Some bleeding is common after u have sex for the first time but can also be due to ovulation.Start a reliable method of contraception and use condoms.
