Destiny • I`m destiny, my so and I have had two miscarriages and then 1 chemical pregnancy/mc I have a beautiful healthy 4.5year old. My wife and I are trying for baby number 2.
I'm having very very light brown sometimes when I wipe!! I'm so scared because I have had 3 miscarriages in the past, I pray that this is not what is happening! Please has this happened to anyone before and it have been normal?
