Miscarried last night

I was 4 weeks 4days and suddenly started bleeding profusely and ran to the ER. I had low hcg levels in the beginning and while they were in the normal range, I felt there was something wrong with this pregnancy. I couldn't get emotionally attached to it. Even after telling people, I felt like I wasn't excited. I kept thinking of genetic issues even when there was no reason to be thinking of it. We used pressed this month for the first time and maybe it had something to do with it, I don't know. Last night at the ER my urine test came back negative and my blood test said my levels were at 2 for hcg. I'm upset but surprisingly no that upset. I think I knew from the beginning.
