options and fertility awareness

Hey ladies. So Ive been on birth control since I was 13 and I'm now 21 I went on it only about three months after starting my period due to heavy bleeding causing me to pass out. I was on the pill for awhile which I loved but started getting migraines and can no longer be on estrogen. I was placed on the shot....which I hated i bled every single day and was numb to emotion. I switched to nexplanon which I love.:. For the most part. I only bleed every few months however I feel very moody and cry a lot. I can not be on any sort of insert such as iud or Nuva ring due to the shape of my cervix and because I am sexually active my doctor will not prescribe me the progesterone only pill. Has any one had this issue? Does anyone use fertility awareness? Please help!
