Help!!!

Katlyn
Hi everyone. I'm very new to glow and my husband and I are currently TTC baby #1 I am 19 years old almost 20 and he is 22 almost 23. We have been trying for over a year now with no luck, I've used various apps including ovia and a good friend of mine who has used this app to get pregnant every time is now 6weeks with baby number 6 so I decided to give it a try! I've been to an OBGYN and she said I am in great health to get pregnant. So I don't understand why it hasn't happened yet! We stopped "trying" to see if it would work and it didn't, it's starting to take a toll emotionally so Please any tips or recommendations to help me concieve faster would be greatly appreciated!!! 
Thanks so much!!
