Trying to Concieve after 10 months

I found out I was pregnant in last year. This was my first pregnancy and my boyfriend and I were so excited. I went to every doctor's appointment without any problems. The day after my last doctor's appointment (two weeks shy of being 6 months pregnant)I was rushed to hospital where I was told that I had already started labor and that there was nothing that could be done to stop it. As you can imagine, we were heartbroken for a very longtime. My fiancee (proposed to me Christmas day) and I started TTC over three months after losing our son. We have now been TTC for about five months now with no success. We decided to wait that long because we wanted to be able to give ourselves time to cope with the situation that occurred. I don't think I could have made it through this tough time without him and my family members. I consider myself blessed that I have this wonderful support system.
