2yrs married and no baby- feeling sad

Darcy • 31 y/o happily married. Can't have a rainbow w/o a lil rain. 💦🌈 😇mom to 2 Angels &1 rainbow due 3/24/16. IUI/ Clomid
Today is my 2nd anniversary and while I am so happy to celebrate 2 fantastic years w my best friend, I am also so sad. I would have never guessed I wouldn't have children or atleast be pregnant by now. After a miscarriage, testing, waiting, uterine surgery, more waiting, and a BFN last week, I'm feeling very impatient. I know this stress isn't good but I'm just so sad. Just need to vent. Will try to enjoy day w hubby and fur baby.
