sex in early pregnancy

Destynee • PCOS • 2 natural born • pregnant with our letrozole baby🤍
I'm 5 weeks 2 days. I feel like having sex is so scary! Like I don't want to because all I can think is it will somehow cause a miscarriage.. hubs and I actually did today and after I felt crampy. I also have a 4cm cyst on one of my ovaries so I'm just constantly worried something will get messed up😭😭 is it okay to continue to have sex? I just feel so scared.
