Okay so this is a little confusing to ask but here i go... So i just recently switched birth controls. I used to be on zarah and was on it for about 2 years. I just recently switched to vestura and on my 4th day on the new pill i had unprotected sex. He did pull out tho and yes he and i have been tested for stds so im not worried about that i just want to make sure i was still protected. Also i was taking my last few zarah pills and then went straight to the new bc vestura pills the next day. Before having sex. But i was on my 4th vestura pill. Help!!!
