I'm tired of trying....

This was month 8 of us trying. We conceived last month but it ended in a miscarriage at 5 weeks :( and AF just showed up this morning. I'm so tired of trying. It's so depressing but I'm also feeling like I'm becoming numb to it all. I've been taking Femara the last two months since I wasn't ovulating on my own and that's been working. But I'm just so tired of the let down when AF shows up. I'm starting to think maybe I am only meant to have 1 child, since we have a 3 year old boy. I don't know. I'm just over it.
