What’s the birth control?!??

HELP! I’ve been on birth control before but got it after only 3 months. I was on the Depo when I was 18 and gained weight and had terrible spotting. I’m still with the same guy and we use condoms but I get so scared. I want to get on birth control ASAP but I don’t know what’s best or what my options are. I went through planned period previously and liked my experience there. I want to do through them again but am unsure if I have to go through my insurance now or if I can still get it for free being older now? Whats your experience getting it without insurance and what do you recommend??!?
