Weight gain

Caitlyn • Teacher. Wife. Northerner for life. Boy mom and pregnant with my 2nd 🤰🏼 ❤️

So I’m 17 weeks along, and so far I’ve not gained any weight?... when I went in for my 8 weeks appointment I weighed 116. And still now when I weigh myself daily it fluctuates between 114-118. Is this normal? I feel like I’m eating, I’m not feeling hungry etc. do I need to just make myself eat more? Or is this okay? I go back at 20 week(so 3 weeks from now) and I can ask my OB. Just curious if anyones already experienced this before. For reference I’m 5foot. So my weight of 116 to start was a healthy weight. Not under or over etc.
