weight issue !!

Just another question i lost alot of weight when i had the mirena in dont know why maybe because i was so sick , but after having it out ive put on a lot of weight especially around my belly its awlful and i havnt changed my diet or anything and i just keep putting it on im the heaviest ive ever been ive put on 11kg dont know what that is in pounds in 9 months do you reckon its because my hormones are out of whack i just feel like a real fat pig at the moment
