New to this and a few questions.

Hello! I am so new to this and still trying to figure out the app. My boyfriend aren't exactly trying because my BC messed up, and ended up giving me two periods weeks apart. But we are open to the idea of bringing a child into this world, we have talked about it plenty of times and are ready to go through this together if it happens. But I just have few questions, has anyone ever experienced your BC giving you two periods a month and then after going off of it, not having AF visit for months after? (AF didn't visit me for 5 months just had a regular period at the end of july). And before you conceived did anyone have dreams sorta of telling you, you were going to become pregnant really soon?
