I’m on Tri-Sprintec and was recently with my bf during the last couple days of a 10-day antibiotic prescription (Ceftin) for a sinus infection. While I was taking that, I missed two pills on different days in the same week. According to Glow, I was “ovulating” right when I was with my bf.

He didn’t finish in me, but I know for sure and certain that there was pre-cum. Should I be worried about pregnancy? Missing pills is dumb anyway, but I’ve heard that antibiotics can lower the effectiveness of bc. Anybody know?
