Don't know what to do

Tina
I am getting more and more depressed! My husband and I have been TTC for about 3 years now! Everything with me seems to be working fine! And I am doing everything in my power to help make this happen! I am even taking some medicine to help ovulate. I took the first round at the begining of the month and I had high hopes! But with 2 BFN and AF coming 3 days early all I feel is defeated! I am so depressed and disappointed! I don't know how to keep my head up or keep trying! It just hurts so bad! Any advice???
