"well, it seemed like a good decision at the time. insertion was fine- one mind numbing cramp but over pretty quickly, but i&#039;ve always been pretty easy when it comes to periods and the like. by day three i was feeling well enough to have sex, despite the dryness. day four- learned that post-sex cramps are apparently a &quot;thing&quot; with iuds. so that was fun (not) day five- horrible dryness and, what&#039;s this? day six-a yeast infection?! is that a side effect of skyla? i don&#039;t remember reading that.. oh, apparently &quot;vulvavaginitis&quot; aka any sort of angry vaginal infection includes yeast infections, and occurs in like 20% of users, way more with skyla than mirena. preventing pregnancy by vaginal hell-fire! not a satisfied customer."
