TTC after a chemical abortion.

Now before anyone passes judgement. I was raped by a man who has been on ever drug known to man since he was a teen. He was 32 when he raped me.  I got pregnant when I found out I was disappointed even though I've been wanted a baby for many years. After going to the doc at two months there wants a heart beat. Dr said Bec of the  circumstances. The baby was most likely won't get one and suggested a chemical abortion to prevent infection.  Now it's two years later and I'm trying to have my dream child. And one else gone through this kind of pain? And now TTC.?
