Trying again

My boyfriend and I started trying again in May, after a miscarriage in February at 7 weeks. We were devastated and I wasn't sure I wanted to risk it again. I have 3 healthy kids from my previous marriage, the youngest being 3, and I've never had any issues. I'm worried about trying again, mostly worried about another miscarriage, I'm not sure I could emotionally handle it. Currently ovulating, so we'll see what happens in a few weeks.
