TTC at 19

I've always wanted to be a younger mum. I have had 4 accidental pregnancies that all ended in miscarriage. I live in my own place with my boyfriend and I work as does he. He already has a baby. And we've spoken about TTC in about 3 months. So I'm going to start taking vitex and folic acid on a daily basis. I seriously hopes this whacks out my system and helps me have a happy healthy pregnancy in which I know I deserve and I can't wait for 2020 to start my fertility testing and find out how to get that rainbow baby I've always dreamed of having.
