My period is 60 days late

So my period is 60 days late 😰 and I know I'm not pregnant because i took a test around 2 weeks ago but I've been gaining weight and feel not myself at all. I've always had irregular periods so I wasn't that concerned at first but now I'm freaking out. Could i be pregnant? Or could it be something bad? ( PS me and my boyfriend don't use any birth control and we've been trying for a baby for the longest.)
