trying to conceive horror

I'm 28, married, and never been pregnant. I been trying with my husband for 6 years. I know some may say I'm young, but my lifetime goal is to have a family. I have been to fertility doctors and OB/GYN. My husband does have a low sperm count.  I have PCOS and have been trying for years. Medication isn't helping and I'm not sure about IVF. I'm depressed and don't know where to go or how to achieve my life dream. Sad.....
