I think this really varies from person to person . I got an IUD and I have two other friends who got theirs as well . I got Mirena placed during my period after being given Ibuprofen in the office , which meant one week of an extra crampy period . After that I ' ve spotted for 3 months and have no more period now . A friend got Paraguard and her insertion was also easy . She was going to med school at the time so she basically had no time to take off even if she had to . Luckily she was totally fine and was having sex by Saturday . Another friend got Paraguard while she was away in college . She took the week easy but was pretty much normal , functioning by the end of two weeks still went to class , did all her sorority stuff during those two weeks too .
