I’m finally pregnant!!

I have two beautiful babies that I am very blessed with. When my son turned 1 we started trying for our third. I have hard pregnancies and I also have a history of miscarriages. I had one before my daughter and one before my son and three chemicals since we started trying for the third. Yesterday I found out I was pregnant! 🙌🏻 it’s a very faint line and today is a little darker than yesterday. I ovulated on the 24-25 of May and I have a 35 CD. Is it okay if it’s faint still? I’m just worried. I don’t want to have another miscarriage. I want my rainbow baby! I go to my first prenatal appointment July 9th!
