2 months without periods??🤷🏼‍♀️

I’ve gone 2 months without a period, I’ve been feeling dizzy and been getting on and off headaches, I think I’m putting on a little weight. And last night I was really struggling to sleep tossing and turning trying to get rid of this sickly feeling and when I did get to sleep I had an unusual dream which i was told I was pregnant 🤔🤷🏼‍♀️. The morning before that I was up at 6am feeling sick and ended up having to eat something to get rid of the sickly feeling. I have taken 2 pregnancy tests ( clear blue) which was taken a week apart from each other and the results came back negative. Does anyone know what is happening or what I should do? I’m soo confused 🤷🏼‍♀️
