Condoms keep breaking

Eden

For some reason every time I have sex the condom breaks and I don’t understand why. I’ve used lube and bigger condoms but it doesn’t help. I would take birth control pills but last time they made me gain a bunch of weight. Considering the ring but it’s so expensive without insurance. I’ve taken so many plan bs because of broken condoms it’s crazy and I know that’s unhealthy. Any advice?
