TTC after 9 years of birth control

My husband and I recently decided that we want to start our TTC journey in April when my birth control supply runs out (I have them mailed 3 at a time). I am 23 and started taking birth control at age 14 to help with painful periods. I know that it will happen when it’s suppose to happen but I am really worried that it will take my body forever to get back on track and start ovulating. I want a baby so bad and I’m so nervous that it will take forever and I will get discouraged. HELP! 😩
