Feeling frustrated…

So I’ve never had regular periods. I can go anywhere from 2-4 months without a period, but since having my son I started having them every month for a while, then every other month, then for three months I had one every month. We’ve not been trying for another just yet, but we’ve recently started talking about trying again and of course now I’ve gone back to no period at all for the last three months🙄 I’ve tested 1-2 times a month and all negative, but I’ve not used any OPKs because we weren’t technically trying. So I’m not sure if I’ve even been ovulating🤷‍♀️ Not sure if I should go to the doctor over it because I have in the past and they basically just tell me it’s nothing. Have any of you been in the same boat and found something that has balanced out your hormones to give you normal cycles? (Besides birth control)
