Depressed

Very down in the dumps today been very irritable toward everyone. I would've been 34 weeks pregnant this week and my husband and I are trying to get pregnant but he doesn't want to have sex. I'm ovulating today and he just wants to sit on the couch and play video games. I just want to cry because so many people are announcing they're pregnant and we've been trying for so long and I feel like a failure because I can't get pregnant I do not know what to do anymore. I feel a meltdown coming on I feel like I'm going to burst into tears :(
