abnormal uterine bleeding
"It is safe to say that after reading these reviews I was more than a bit anxious about the whole process.Eventually I decided that until you try then you'll never know; everyone is different. 

It was the insertion process that had me worried, but it turns out the discomfort is only very temporary. I've had worse (and longer lasting) pains from sports injuries.

The whole process took about 10 mins and, during the application, it felt like having very bad period pain cramps. After the process was complete it just felt like mild period aching, nothing unmanageable. One day of carefully taking paracetamol and ibuprofen was enough. Enough so that I was able to go to my sports training! Since then there has only been mild aches every now and then"
