Serious question..

So I was treated for clamidya a couple months back and got rid of it, my ex and I got back to better which was probably stupid. He said he got it cleared up but he cheated on me again with the same person who gave it to him...

I’m 8 weeks pregnant, IF for some reason I got it back from him, is it going to affect my pregnancy? I don’t have an appointment till middle of next week and I read that having that particular std can cause miscarriages. And now I’m freaking out. Any tips if you’ve had it and found out and it didn’t do harm to your babies ?
