"i had skyla inserted 8 weeks after having my 2nd child through c-section. the insertion was very painful but quick about 5 min, i had some moderate cramping few days after but nothing serious. i was breastfeeding at the time, not sure if it&#039;s skyla&#039;s fault but i lost my milk supply almost completely after getting it inserted. i only had one period after the insertion it was much heavier then my normal period, lasted for about 5 days with very heavy bleeding on day 2 and 3. and 3 months later i fond out i was pregnant, so much for 99.8% protection."
