Help Me Complete My Family

I have been trying to conceive since August of 2018 with no success. My husband has already been checked and his sperm is normal. I have previously been put on Metformin and Clomid, but still haven’t been able to get pregnant. I am also keeping track of my ovulation and period using an app. I just had my first consultation with a fertility specialist and in order to get started, I will need to get various tests, such as egg count, and my tubes checked to make sure they aren't closed. This will cost me $1,000, so any help would be greatly appreciated.
