gained weight for the first time in a year :/

i started calorie-count about a year and a half ago. i reached and then even exceeded my goal with a 32 pound weight loss. apparently since i lost so much weight, my hormones got completely out of wack. mood swings, acne. whatever. so last week i got back on birthcontrol (nuvaring) and have gained back 4 pounds. should i be worried? i switched back to weight loss calories instead of maintenance until i get this figured out. help?

VERY unlikely that you actually gained 4 lbs in one week. it's probably mostly water weight!

my boobs went up a cup size and i've had like 2 people tell me my legs look bigger. i mean, i was exceptionally thin before so maybe my body is just adjusting to all the new hormones?
