Cramps After Sex??🙊🙉🙉

Good Afternoon Everyone. So my husband and I have been... how do you guys say it lol... TTC since my miscarriage back in April.. I've been praying that this month will be the month, and that I'll finally be pregnant with my healthy twins... So... last night, we had sex, and he wasn't rough or anything, and afterwards I started cramping really really bad, almost to the point where I was in tears. Has This Happened to anyone else? am I just crazy? Lol orrrrr am I finally pregnant lol! I'm so tired of seeing not pregnant on the stick, so I'm contemplating just waiting to see if I miss my period.
