Is it possible ?

I had a miscarriage a couple days before Christmas we got the test results back and she had Turner syndrome so they believe that is what caused the miscarriage. Well my boyfriend and I got drunk on Saturday probably too drunk and emotional and we had sex is it possible to get pregnant a couple weeks after your miscarriage? I'm really hoping not because after 3 losses and this one being so horrible and painful I need a break. Do you have to wait for your period before you even start ovulating again ?
