IUD and possibly pregnant

Hi guys

Please no judgment

So I’m really stressed right now, I had a termination due to sexual assault and I got the Marina IUD put in.. I am 6 weeks post procedure and I read that he can take your hormones (hcg) a while to go down

I went for my dr check up and she said that it should have dropped by now and gave me a referral for a blood test

I know it’s like 1% chance but freaking out

Anyone heard of this happening ?
