Hey ladies! My boyfriend and I have been having sex for a while now. The majority of the time we're safe about it (condoms), but sometimes not so much. He's never cum inside me, but he's had to pullout because he was about to. This was Thursday- June 8. I started my fertile window on Friday/Saturday- June 9/10. I've been nauseous for the last 3 days, periodic headaches, sensitive nipples, heavy boobs, and just overall exhausted. Your thoughts?
