I can't do this anymore.

A year ago we decided to try for a baby. We got pregnant on the first try and I thought life was great then 11 weeks later I had a missed miscarriage and our life's were very sadden with our loss. We started trying right away and we are going on 10 months trying and nothing. I thought we might have gotten lucky this month. On cd 8 I had light cramps and my resting heart rate slowly started rising from 63-65 to 75 and up. But now I'm cramping again and I think that is my sign I am not pregnant. I can't do this disappointment any longer. My heart can't take anymore. I'm out... good luck ladies I hope you all get you little one. 😢
