I’m so ready to give up

So I’m on cycle day 80. Yeah I said EIGHTY. And I’m technically 48 days late. Negative test after negative test I honestly don’t know what to do about it anymore. I’ve just been getting more irregular as time goes on. It’s been 3 years since I had my son and I’ve been so irregular since. We tried conceiving for over a year now and nothing. I think it’s time to give up on it and start taking birth control because I feel like my period is just never gonna happen. Also there’s no way it could be menopause because I’m only 20
