Hello there.

My boyfriend and I had unprotected sex (it was also my first time) early last week, about 2-3 days after my period ended. I have birth control (Ortho Tri-Cyclen), but had been waiting to start it until the Sunday after my period, which was taking a while because my periods are always irregular. Well, we had sex, and decided to use Plan B as Emergency Contraception, about two days after taking the Plan B, I began to bleed again, not for as long as my period usually lasts (only about 2-3 days) but definitely as heavy. The bleeding has finally stopped, can I start my birth control now? If I do, how long until I am fully protected by it?

I am also on Levothyroxin for my thyroid, this has a tendency to cause one's periods to be out of whack as well.

Any assistance anyone could offer in this matter would be greatly appreciated!

Thank you!
