Advice please!

My husband and I have been trying to convince for 2 1/2 yrs with no success. I've been diagnosed with PCOS. Everytime I find out a close friend is pregnant I get really hurt just wondering why not me. Last night I found out my bestfriend is pregnant and I broke down crying. I told my husband I want to have further testing down to see if there's any possibility of me being able to have kids and he's against it. He then proceed to say "I know I can get someone pregnant I've done it before." This happened with an ex in high school. That comment killed me. Idk what to do or say. He doesn't understand how badly I feel like a failure as a women.
