Miscarriage and trying again

I feel so off. I'm sad, very sad. I had a miscarriage and then a d&c on April 10th. We are currently trying again. Every month I have gotten a period I feel devastated and so sad. Every pregnant woman I see I am very jealous of and get sad. I have 3 children and never had to experience a miscarriage. We planned for that baby and was so ecstatic when we were pregnant. Did not even know of a problem until the day of out first ultrasound. Repeat ultrasound a week later to confirm nothing was in there. Just a sac. I just want to have a baby. At this point we would have known what it would of been and it hurts to hear people gloating about their pregnancy. I guess the worst is not knowing what happened, why it didn't work out. I think this time around it is harder on me each month I don't conceive and it brings back all the hurt emotionally from the loss. Anyone else feeli this way?
