Been on bc for 2 yrs, took pill 9hrs late one time. sex on 5th day of new pack, pull out method used. now a lot of discharge, normal? risks?

Likely your ok: It sounds like your pretty consistent with your BC and the 9hr late one time is ok. Just don't keep doing it. But I would advise you use condoms as well for protection from Sexually transmitted disease. BC does not protect you. Pulling out method is not BC at all. If you want a better form of BC, I would advise the implantable Nexplanon or an IUD.
