Appetite and Birth Control/Hormones

Alex • 25, ABD&OB/GYN RDMS
So ever since I've been on birth control my appetite goes from one extreme to another. Week 1 of active pills, I'm super hungry and I eat a lot. My appetite is a monster.
Week 2 is when it's at a minimum and I just never feel hungry, especially in the mornings. I usually eat breakfast every morning but sometimes never feel the need to.
Week 3 is pretty average. I don't really over eat but I eat. 
Week 4 is my period and I can never eat a lot cause I feel too bloated.
Anyone else had this experience? 
I guess you can say I don't gain or lose weight cause one week makes up for the other but it's just scary how it changes suddenly like that.
