Help! Low sperm!

Melonie • Struggling with PCOS for three+ years. Mommy to an angel in heaven, and ttc again.
Hubs is going back to do another test, but the one today shows he's borderline. What are some things we can do to help raise his sperm count? And what are things we can do differently that's going to help us get pregnant. And could this be the cause if my miscarriage? I'm so upset right now. 😞 Having PCOS is bad enough, and losing my baby last month was another blow, but this is just taking it to the best step and I feel like I'm falling and just can't catch a break. 9 years we've been having sex, 7 years without protection, and 6 years actually trying to have a baby. And one pregnancy has resulted from it, and it didn't stick. I cannot keep going on like this without losing all hope of ever being a mommy. I feel so broken. 😞
