Pregnancy Possibility

Jasmine
I was on the Nuvaring and took it out for two weeks and switched to the Implant. The doctor said to wait 7 days before having unprotected sex. 3 days in I completely forgot and went for it, he didn't pull out and the birth control wasn't effective yet. Now my period is 2 days late and I want to know if there's a chance of pregnancy or a side effect of the birth control.
