"i am on day 21. i am 27 years old, married, no kids. getting it put in was the most painful thing i have experienced. there were two major cramps. the first when she measured me, the second when she put it in. i had to grip the table, squirm, and groan a little. i had a very bad few minutes after it was put in. i was dizzy and nauseous. i laid down, had water and i was better 20 min later. i had a few cramps the following days, some bleeding, and black gritty discharge. my doctor said was old blood from previous periods coming out. so far i&#039;ve had a few cramps every few days and spotting. i freaked out at first because i couldn&#039;t feel the strings, but trimmed my nails and found them."
