Cramping after orgasm

Bri

So for the last week I've been having these period like cramps. Last two nights my fiance and I have baby danced and after I would orgasm I would cramp as if my cycle was coming on. No blood no spotting. I've never experienced this before.....I've also been experiencing hot flashes when I'm anaemic. Nausea just laying down and a few dizzy spells. Now I'm not one to think I'm pregnant. I won't even say the word, but let him Tell you I am pregnant. Has anyone else experienced cramping after orgasm and been pregnant? If so how far along.?
