Possibly pregnant, sex with SO and crying

I’m possibly pregnant right now we won’t find out until I go to the doctor Tuesday. I have been having CRAZY mood swings, nauseous/dry heaving, getting nauseous from my burps(which only ever happened when I was pregnant) this has been going on for about a week maybe week and a half. But so and I were getting it on and out of no where I just start bawling and he asks why I’m crying and I told him I don’t know because I didn’t and after I calmed down went right back to getting at it and I cry again out of no where.he keeps saying things like **** your pregnant, or you are definitely pregnant.Today I was supposed to start my period. It’s not unusual for it to be a little late but I’m freaking out.
