So frustrated!

Ashley
My husband and I started Ttc for our first baby in November. Got pregnant in December and miscarried in February. I was crushed. We took some time off to grieve. We started up again may. In June and July I had chemical pregnancies- heartbreaking. Found out I was pregnant again. Praying for my hcg/beta to double at my blood work tomorrow (I hate waiting for the results) I don't understand why nothing sticks! I'm getting so frustrated! 
Is anyone else in a similar boat?
