Cycle Buddy? AF due 3/24

My name is Miranda. I'm 19 years old and TTC #1. I am very mature for my age, and i am ready for a family. I had a miscarriage not too long ago. It really crushed my confidence, but I am feeling better. My man and I have decided to keep trying. I am taking prenatal vitamins as instructed by a doctor. I used to have irregular periods due to hormone imbalance but am on an herbal supplement called Vitex Chaste Tree that is helping a lot. I am still sometimes a day or two off, but no where near as major as it used to be. My man and I have been TTC for over a year. Maybe a cycle buddy will help boost my confidence a little.
