Mirena

So I’ve had the mirena in for 6 weeks. Since the day I got it in I’ve been bleeding/spotting/ cramping every day. Sometimes it’s days long and heavier than my normal period was. Online says this can go on for 6 months. It’s literally making me depressed and I feel nasty and bloated all the time and this summer it’s not fun to have to bleed and carry pads and tampons everywhere I go! My Dr wants me to try it for 3 months before just removing it but idk how much more I can take. Having a 5 day period sucks, now it’s been 6 weeks. I’m going crazy and it’s super annoying. Someone please shed light on this if you’ve had this happen with the mirena. Thank you!
