MommaA's TTC after m/c Wish

Had a m/c in feb and got told my baby days may be near an end as me and every other female in mothers side of family are burdened with every form of cancer in uterine, oaries and a histerectomy (sp not correct!) Is in my near future. I'm 28 with 2 sons I'm very grateful to have but remarried and want nothing more than a baby to complete my new family. If it can't happen, we'll survive. But its all I want and would never ask for more. Trying to conceive by Nov before next dr apt. I wish I wish!
