Y’all are going to think I’m crazy

So the past two nights I feel like I have a orgasm in my sleep followed by bad cramps for about a minute then stops.... so this morning I had another dream where it feels like I orgasmed in my sleep and the cramps woke me up again and now I’m up at 6:00 in the morning on a Sunday.... soooo not normal for me but the cramps don’t last long at all...? Anyone else experienced this ? Could it be a early pregnancy symptom? I’m 12 dpo today!!
