Does anyone else sometimes feel like they don't trust their pill?

Shauna
I'm on combination birth control and I take it perfectly. I like to use condoms along with my pill but last time I had sex was just over 2 weeks ago. We didn't use a condom but he pulled out. I'm on my break week now and I got my withdrawal bleed. It's a normal flow like it always is yet for some reason I still get paranoid about pregnancy. I'm trying to get better at trusting my pill and not run out and get a pregnancy test after everytime I have sex lol. Does anyone else get paranoid? Do you think there is a need to get a pregnancy test even though you get your withdrawal bleed?
