I don't know how much more I can take.

My husband and I have been trying so hard to have a baby. It seems like every month we both get our hopes up thinking this is it and then when the time comes I'm in tears and he's let down. I've been tracking everything, I've been taking fertility supplements, and making sure I stay active and healthy. It seems like no matter what I do it just never happens. I don't know how much more I can take with all the false hope and let downs. My husband is very supportive and tells me not to give up but it's so hard not to. What more can I do?
