How to body build as a VERY petite woman?? 4ft11in 100lbs

I'm very petite, 20 years old, I weigh 100 pounds exactly, however it seems like most of my weight accumulates in my stomach so I would like to lose about 5 pounds before I try to build muscle mass. I have tried to do this a few years ago but ended up always feeling dizzy and light headed because myfitnesspal told me to eat 900 calories per day to lose 1lb per week. 900 calories did help me lose weight at a normal rate but I felt terrible and weak while doing so. (I also went to the gym 4-5 days per week).

I feel like I can't lose weight because my maintenance calories are about 1500 per day and I regularly work out but I still have a hard time eating less than 1700. I'm scared if I cut too much I'll feel weak again.

What do other petite women do to lose weight? How many calories per day should I eat if I work out 4-5 days a week?

I really have no idea how to go about this considering there isn't much information out there on how to lose weight and then bulk as a very small woman. It seems like because I'm so small I don't have room to cut calories without starving myself and can't eat much more than 1500 or I'll just keep gaining weight.

ps - I've also heard of recomp diets but not sure if that's a diet I should look into.
