Constant disappointment

I've never written one of these before but I figured I would say a few things about me first before I start crying again. I'm 33 years old and my husband of 2 years is 35. I know I probably shouldn't cry, complain or even be upset but every month AF comes and it's just more and more disappointment that I still haven't become pregnant after trying since June of 2016. I feel ungrateful but sad at the same time as I already have 4 children(3 pregnancies) and my husband has 3 but we have none together and we would just like to have one before I have to have a hysterectomy. I love my children and he claims them as his own but I feel like it's starting to become depressing for both of us. I was recently told that I had ovarian cysts and a fibroid. My doctor told me that it wouldn't be a problem but even with a round of Clomid nothing. It also doesn't help that my husband is an OTR truck driver I only see about 6 days a month. My parents aren't happy about us wanting another child but we have the means to support them. Does anyone feel this way or is it just me?
