birth control
"Skyla was super easy to have inserted. Get an experienced doctor. It literally took like 20 seconds. I would categorize it as really uncomfortable. But have someone there to distract you and is not bad at all.  It wasn't painful. Also, get it done during your period, sounds like it makes a big difference. 

If your doc offers anti anxiety meds, take them. If they don't, ask for them, then take them. It helped me. 

After the insertion, no more pain, just regular period style cramps."
