Pregnancy weight gain at 14+3

Hi y’all. Anyone else weigh themselves and just know that at least SOME of the weight gain is due to constipation/not being able to poop?! I’m 14weeks 3 days and haven’t been eating too much— I’m still pretty nauseated. As of today I’ve gained 5lbs. This feels wild- like way too much. I haven’t really pooped (sorry tmi) in a week. I mean not REALLY. Doctor knows- says it’s normal. Told me to take colace and drink some prune juice. Anyway, I feel like that 5lbs isn’t accurate. I don’t know how to manage accurate weight control and pooping at the same time 😂 any suggestions?!
