normal or pregnant?

Okay.. so my daughter will be one on the 29th of this month.. I stopped breastfeeding when she turned 10 months... in October, I received my first period. It lasted five days! Well, I have missed my second cycle since then. I know that after you breastfeed , your period will become irregular.. but I'm getting scared! No birth control.. and my husband and I do not believe in birth control! However, he got a little carried away.. 😂 but anyway (tmi).. I've notice every time I eat- I look /feel pregnant! No breast tenderness. I was dizzy a few times.. I been using the rest room a lot.. 4 negative pregnancy test. Could this be hormonal?
