New mom, new to this

Hey y’all. Need a bit of perspective from people who have been doing this longer.

I’m 28, new mom (weaned off breastfeeding right when I started IF), 200 lbs, 5’4”, desk job. Only been doing 16:8 for a week and sticking to ~1800 calories, but have gained 2 pounds since I started. Any tips? Is it too early to see results?

Should I go for fewer calories? Eat at specific times throughout my window? Much appreciated

Edit: one problem i know i have is drinking enough water - i drink like a cup a day
