Help me

Ok so me and my bf use the pull out method and I’m not on any birth control. I got my period a week early but before that I was nauseous and tiered a lot, cramping, back pains, and headaches. But today out of no where my bf just gets really nauseous and tiered. I’ve been google that and it’s says men can have Morning sickness and you can also still get your period if pregnant. I have know clue what todo and I’m starting to panicking. Can someone please help me.
