IUD HELP

Lagabychula

I’ve been concerned lately because I got the IUD a little over a month ago and I have smelly discharge and have been spotting through the whole month andddd got my period earlier and it doesnt seem to end!!

Also when I make any over strenght like going to the gym and doing weights.. I get cramps....

Is this all normal? How long until it’s over!?!? Jeez!!!
