Plan b while on borth control:

Maddison
So me and my boyfriend had sex last night and he didn't 100% pull out. I had to switch birth controls and I've been taking my new birth control for about 8 days. I'm nervous that I could get pregnant due to he lack of days I've been on it. So I thought I should take plan b.... Is that a smart decision or am I fine. I'm just nervous! Needing help and guidance.
