Am I pregnant?

Earlier this year I had gained some weight and my breast started leaking milk for a month. After that month they stopped and the milk never showed up again. I had recently stopped my birth control in January but in May I started to get 3 day periods when I usually have 7. A lot of of the food I like lately taste different, I’m hot and feel dehydrated a lot and my breasts have seem to grow even more. I don’t see how I’m gaining when I barley have an appetite throughout the day. Any advice?
