Can’t Lose Weight

Hi everyone! I’ve been trying for about 6 months to lose weight, but it’s not happening. I had a baby June 2019. My usual weight is 130-135lbs. Currently, I weigh 150lbs (5’4) I didn’t become consistent with working out until late February. I do circuit workouts, and I don’t eat too horribly. I don’t know what else to do except for a drastic diet (atkins), fast/juice cleanse, or surgery. I have never had issues with my weight or body so this is all so new to me. And it’s making me self conscious af. Any suggestions would be helpful. 😩
