TTC after stillborn

I had a miscarriage at 7 weeks in 2011. Several months later I was excited to know that I was pregnant again. After a very healthy pregnancy, on Easter Sunday 2012 I delivered my perfectly healthy son at 30 weeks stillborn. We are completely devastated and confused from our loss, but we finally decided to start trying again in September. I have been pregnant 3 times with two losses, but have never had any problems trying to conceive up until now. It's been 8 months since we loss our son, and every single month that I get my period, it's like reliving my loss all over again. I swear everywhere I look I see pregnant people or people that I know are telling me they are pregnant. It's difficult not to be jealous or envious all though I am happy for anyone that can get pregnant knowing how babies are true miracles....Just wondering if anyone else is having trouble conceiving after a 3rd trimester loss of a healthy baby? ugghhhhh
