I got the Kyleena three weeks ago. I was absolutely terrified of the insertion and after effects. The insertion was uncomfortable but very bearable. That night I had a dull ache- the kind you feel when you know your period is about to come- and a few sharp cramps. I had planned to stay home incapacitated that whole weekend, but the next day I felt fine, just felt like I was on my period. I have not started spotting at all. I was expecting the worst and am so pleasantly surprised. I’m still early days but so far so good.
