HUNGRY

So I had a belvita cookie, a playa bowl, and dinner. 30 minutes later I was still hungry, had another dinner. 39 minutes later I was still hungry, and had a yogurt and a large coffee, and I felt weak like I haven’t eaten, so I had cheezits and a bag of gummies and two macaroons and I’m still starving. im bloated and constipated and I got my period for like four days two weeks ago after taking plan B (probably shouldn’t have because I used protection when I had sex I’m just paranoid), but can someone explain to me why I am so hungry?? Is this normal?
