Ttc for the last 6 months but this round I used glow for the first time.

Since I was 9 I've had irregular periods. I've been put on many birth controls and the last one being the depo shot which made me gain 50 plus pounds. I've always been overweight. I got diagnosed with binge eating disorder about 4 months ago and I was put on Vyvanse. Since then the last 3 periods have been every month. We would ttc but I didn't know how to track my ovulation. Until my bestfriend introduced this app to me just in time after this period ended! I am on my last Green Day with 8% chance but hopefully we had enough playtime during the right times! I had a miscarriage in 2011 and I've had extreme baby fever ever since! But now that I am with a better man and once our house is finished being built we will get married. He wants this just as bad as I do! I need all the baby dust I can get and also any advice and help would be greatly appreciated. I don't have pcos I got that checked and my thyroid is good to go. What are some symptoms that you would know your pregnant and when is the earliest I can take a test.
