curious what others!

we have been trying to conceive for a few months now. I have PCOS and endometriosis, so we know it will be a challenge. I started on Metformin for a month, and then took the five days of Chlomid. I was due for my cycle on the 10th of June, and it hasn't come. about a week and a half ago I tested and had a big fat negative. Now I'm exhausted all the time, my stomach is rock hard when I'm standing, I'm so emotional and feel like I can eat everything in my house! any advice would be appreciated!
