Feeling Helpless 😢

Husband and I have been ttc for 3 years. I had a hysterscopy with D & C on 1/30/2015 for pcos related cysts. Thought I was having implantation bleeding since I'm not supposed to start my period for another week, and it's very light spotting. Hpt say I'm not pregnant, and it's depressing, such an angry and frustrated person I'm becoming.
