Heeeellpppp!!

Never had this done to me before I'm 21 years old. So I recently got off of birth control pills 2 months ago but this month I stopped completely without skipping or anything like that . Me and my fiancee is trying to start our own Little family because we're very ready for that big step. But so our sex is unprotected. For 2 weeks I noticed Everytime I do my business in the bathroom on my toilet paper I've noticed something kinda dry but dirty (brown color) ... I'll like to say that it looks like old period blood but not really at the same time bc it's very dry. I've never had old period blood that's dry asf and lasted for 2 weeks (I'm currently still doing it) . I have no idea if my body is reacting a certain way since I weaned myself off the birth control . Or whats going on. Need advice and opinions please!?
