Mirena coil

I had the mirena coil fitted 2 weeks ago today and had menstrual pain for about 3 days after that and then felt nothing which was perfect! But today I’m having really painful cramps off and on but I’m not due for my next period for another 11 days!

Has anyone got the mirena coil and had any problems like this? Not sure if It’s normal or if maybe my coil has moved or is coming out 😩

Any advice?
