Can I b prego ? Help 🤦🏽‍♀️

I’m on birth control pills nd I take them at 9am every morning later on one day I had sex with my boyfriend nd he busted in me (that’s normal cause we do it all the time never got prego) BUT I didn’t go home that night like I was suppose to and I didn’t get to take my pills the next day and then we fucked again later around 12 but he pulled out. So is it possible ?

UPDATE: I’ve been having pain in my stomach and just haven’t been having an appetite. Today I have white thick discharge.
