WTF?! 😭

I've been off of my birth control for about 2-3 months now after being on bc pills for 7 years. I got on the scale this morning and almost had a panic attack!!!! I've gained around 13lbs since being off. I haven't been running like I use to and it took me so long to get to where I wanted, weight wise, and now it's like everything I do, the scale keeps climbing!!! Whhhyyyy???? This is making me so depressed! Anyone have any tips? Advice? A magic weight loss trick? 😭
