Loosing hope...

li
It's been 2 months since my last miscarriage, it took a hard blow to the heart for me. It was my 3rd miscarriage. Me and my fiancé have been TTC for a year now and still nothing. We have a healthy sex life, at least twice a week. Every time I have my period it kinda breaks my heart a little each time, and my fiancé doesn't really understand why it hurts so much, because at 13 I was beaten into a miscarriage at 3 months. I want to have a child so bad, but I just feel like I'm never going to have one... my period is due in a couple days and my mood has gone down to depressed because it just another disappointment waiting... what should I do?
