Sex while cramping?

I found out like a week ago and estimated like 4.5 ish weeks now. But I’ve been cramping. Like since I found out but read that can be normal feels similar to pms cramps but not as severe as when I am bleeding. But I’ve been scared to have sex because of it. Sex helps my cramps but unsure if I should even try that it’s my first pregnancy.. also because it helps cramps I usually started my period in the past like a day or two after I did have sex so I’m nervous idk why. Any insight?! Would I be safe or should I wait? I don’t see the OB until I’m 10 weeks so I can’t ask rn. I’ll be fine waiting if I should of course but like im sure y’all know how the hormones be when you really want it lol.
