Cramps

So I have a few more days until my period and my hubby made me orgasm and I got a really weird cramping. Usually before my period this’ll happen and I’ll have what feels like every “pregnancy” symptom in the book lol. But now something makes me wanna say I’m pregnant and I’m not feeling any symptoms of even my period and so I’m like well no I’m not pregnant I always think I am before my period. But this cramping was a lot different and a lot quicker than usual and I was wondering if this has happened to anyone before they found out they were pregnant??
