"pros: pop it in, wait three weeks, pop it out.  replace right away to skip a period (this never really worked for me, but i could stretch it out some if there was a date i wanted to skip. i could never convince my body to skip a whole month. my periods were much lighter and shorter on nr which was nice. 3-4 days usually, medium to light flow.

cons: no libido.. which i guess is what really makes this work, i did not want sex from my husband. i could do the deed, but there was no passion like before. sex became completely irrelevant for me. i basically formed an indifferent opinion of my husband. i took a break for a month or two to see if i felt more like myself, and i did, but i also ended up pregnant with baby number 3, whoops."
