This is my first month taking the pill and I'm on the last row and I took my third pill last night it's still early in the morning now, and last night I thought I was bleeding cuz I seen a little blood but when I used a Tampon there was nothing there when I took it out 2 hours later, and I also had sex with my bf and the condom broke but he didn't ejaculate, could I be pregnant and if so what should I do
