Fed up with Hormonal Birth Control

I am fed up with birth control and it’s side effects. I wish being under 18 and not sexually active and not taking birth control or worrying about it. All of them have side effects. Unnatural overall. I have shifted my lifestyle to a more homeopathic natural way of living. I’m vegetarian trying to go vegan soon. I just want to have the best quality of living because I get fed up with feeling sickly. I am only 21 and have tried almost all of them and the ones I haven’t tried is because I don’t want too. I want to try and track my own fertile time with a temperature and checking cervical mucous. I am afraid because I am starting nursing school and I can’t afford to get pregnant. I am also married and I feel ridiculous trying to have my husband where a condom. Just had to rant. I am currently on the pill it is causing problems. I was on the depo and I was all over the place emotionally and bled awful in the beginning.
