Miscarriage

Hey guys. I'm devastated after only knowing I was pregnant for a week I miscarried on Thursday. My hcg levels then was 20 and on saturday they were 8 (I was 6 weeks so they should have been at 4000).

The nurse I saw said I should bleed for 2 weeks and then 3 weeks after should get my period and the bleeding would be really heavy.

However I finished bleeding monday morning, and it wasnt as heavy as my normal period. Has anyone else had the same experience where they miscarried but had no heavy bleeding? My cervix was closed on thursday.

Also has anyone who miscarried had sex after the miscarriage but before their next period? My partner and I both want to but I dont know if this makes me a horrible person for already wanting to be intimate with my partner. Xx
