Possibly pregnant after taking only 3 days of BC pills, then stopping?

I have been off BC pills for over a year now, but just recently found an old pack, so I started taking them. After 3 days, I became EXTREMELY moody, so my boyfriend insisted I stop taking them. Of course, I got the fake period when I quit taking them, even though I had had my real period the week before (I was a Sunday starter with the pills). During the fake period, we had unprotected sex, in which he came in me. We have also had sec where he came in me 3 times since, after I had stopped bleeding. Could I possibly be pregnant now? I'm just not sure that I could because of the way I messed up my cycle by taking a 3-day dose of BC. As of right now, Glow says my period should be starting on the 9th of April. (P.s. We had all the unprotected sex during the days I was most fertile, according to Glow, even though I was bleeding lightly due to the BC). Any advice would be greatly appreciated. Thank you!
