HELP! Constantly hungry!

Candice • After two years of trying me and my Fiancé are so pleased to say we are having a baby!! God bless ❤️
I am always hungry! I will cook up a yummy healthy lunch then an hour later I am starving again! I am drinking lots of water and herbal teas. Hoping to curb the crazy appetite but it doesn't do anything. Only time I am not hungry is when I wake up. I don't want food at all. And normally I love breakfast. But I am gaining more weight then I feel I should be.. I am exercising lots to try and keep myself feeling fit but it isn't working. I look massive and I'm only 17 weeks.... any suggestions?? I'm 5'2 and I feel like I'm as wide as I am tall lol. But seriously... 😓
