Gaining weight while training and keto

I need help!

I'm a 28 yo female, 5'4, 135lbs, no clue on BF%

I have been straight cardio and keto since three years ago when I had my daughter. Got down to my normal weight of 125-128lbs by 1,200 calories, low carb and pretty much walking on the treadmill everyday... Once I got down to where I was, I never increased calories..

Fast forward to January, after the holidays, I decided to get strict on my diet and work outs again.. Thinking I was gonna tone up and lose some body fat, NO!!! I GAINED!!

I don't weigh myself often, I just judge by how clothes fit.. and they keep getting tighter and tighter..

I weigh all my food, track my workouts with Apple Watch and a Fitbit! I get anywhere from 15,000 - 20,000 steps a day..

I've recently added HIIT work outs, 2 rounds, followed by LISS - 30 mins of it... ( Body weight squats, lunges, sprints, hill sprints, planks ect) I try to exercise almost everyday but no less than 6 days a week..

I have been trying to change up my workouts, I tried upping my calories to 1500-1700... nothing! I just keep gaining..

I follow a 5% carbs- 25% Protein and 75% fat diet.. its hard for me to hit 1500 cals a day bc I'm just not hungry and no, I do not eat my workout calories..

Some weekends I might go up to 2000 calories but I account for everything! Nothing doesn't get weighed or put into MFP..

I'm at a loss.. I should be losing! I know what everyone is goin to say is input vs output but I'm telling you.. I don't eat my exercise calories... I weigh and track EVERYTHING..

Could it be hormones? Over training? Under eating? I am so lost... Help..
