Ok, I'm on a tricyclic bcp and am 6 weeks into a new pack, meaning my last period was about 6 weeks ago. Two weeks ago I missed a pill and doubled up the next day like I should and I apparently missed another pill last week (not sure of the day but it was possibly last wednesday) but did not realize the mistake until friday (4 days ago) so I did not double up until then. During this time my bf and I have had sex twice w/o protection and now I'm wondering if I could possibly be pregnant.
