Can birth control be the reason I’m not losing weight?

I started taking Junel Fe 1.5/30 (the birth control pill) in august 2019. I take it perfectly. I’ve always been overweight, but since I started taking it I’ve gained a few pounds, nothing too crazy. When I started the pill I was 227 pounds. I am currently on a weight loss journey (I started the journey on February 18th of this year) and I am 215 pounds, so I’ve lost about 12 pounds, BUT, my measurements are the EXACT same and I am seeing NO results!!! I workout EVERY day and I only eat around 1600 calories a day which is the complete opposite of what I used to do. I used to eat 3000-3800 calories a day and laid in bed all day. Why am I not seeing results? Could the hormones in my BC be the problem? I can’t get off of the pill because my periods are so heavy it caused me to be anemic so I have to stay on the pill. I feel like I will NEVER lose this weight! I just want to be happy! But I’m not going to give up!
