trying for number 2

I've been trying to conceive baby #2 for over a year now and have suffered two miscarriages. My son is 2 and a half and with every passing month I get more anxious and stressed that I still haven't given him a sibling. Getting pregnant with him was so easy I don't understand why this time around is so hard. I finally made an appointment with a specialist because I can't take another month of trying and disappointment. Anyone else in the same boat?
