Red flag?

Alexis

It's been so hard for me to get pregnant... I've been trying for 3 years now... we dont mind if I do or dont become pregnant but I pray about it. I'm in my early 20s which makes me think this will be easy for us but I'm wrong. My boyfriend (soon to be fiance) loves that he can just cum in me whenever he wants knowing it wont make me pregnant. He isnt scared or get that blessed thinking that I could end up pregnant afterwards anymore.... We dont even bother buying condoms. Is this a red flag? Should I get checked out? Should I wait?! I dont know anymore, it makes me feel less of a women...
