Fed up! Venting!!!!

This Sunday will mark my husband and I's 1yr wedding anniversary. We started trying for a baby the night of our wedding. After 7 months of constant negative tests, we finally got a positive, just to find out that at our 9 week apt, there were three babies without heartbeats. We are finally back to trying again and the one night that I am the most fertile, all of his cum comes right back out after sex. 
I am so emotionally tired. Every time I see a negative test another piece of my heart gets ripped out! 
I know that stressing doesn't help but I can't stop wanting a baby. And I am dreading the fact that with that kind of ending I am never gonna get pregnant. 
I bawled, and all my husband tells me is to stop thinking about it and then rolls over and falls asleep. 
I'm so done!! Tired of hurting and the pain just turning into a constant thing that gets reminded every month. 
I just want a baby! My son wants a sibling and having him constantly ask for one just adds to the pain.
