Not sure if I'm doing this right or not? Please help.

Two months ago I decided to become vegan and with that came the entry way of eating way more fruits and vegetables that I had ever consumed and it's a good lifestyle for me. I am maintaining it very well. However, I came down with depression and am currently working to lose the weight I had gained which wasn't much but also the excess weight I still had to lose prior to giving up. My routine usually consists of days where I do abs & legs/butt, legs/arms/obliques, etc and I'll provide an example of my ab/leg routine : (30 star jumps, 30 jumping jacks, 10 squat jumps in between each set) for abs I do 15x5 / Ab twists, Bicycle Crunches, Mountain Climbers, Bridges, Crunches, elevated leg crunches / Legs : 12x5 - Sumo squats, squats, walking lunges, one-leg bridges, inner thigh lifts and rotations.
For arms I do 10x5 for right now; regular push ups, lateral push ups, planks, the little backwards chair pushup (sorry not familiar with names..) and then I lift 15 pounds and do the traditional arm lifts along with the jumping routine I have created. I'm not really sure if I'm doing this right and if this will really pay off nicely or not. I'm really aiming to lose a few inches within 45 days and get more lean but recently everything I eat, I get extremely bloated and lumpy, my stomach hangs over and I'm not sure if this is actual weight gain or the fact I should be starting my period soon. Please help!

Note: I do log the food I eat and generally I eat about 1200-1500 calories a day.
