5 weeks 4 days scared to have an orgasm..

I don't know why I'm scared, but I'm just scared that having an orgasm can possibly knock my pregancy loose or something? Maybe I'm just being paranoid, but I haven't had an orgasm in a month and I REALLY want to, but I wanna wait a few more weeks. I feel like the early part of pregnancy is when things happen more and I don't want to risk it .. Anyone else feel this way or is it just me???
