Yes, and one advantage of having an IUD is that sex does not have to be interrupted for contraception.There is a 24-hour recommended waiting period after your IUD is inserted to prevent infection. This is because the IUD procedure involves your healthcare provider using surgical instruments as it passes the IUD through your vagina and cervix, and into your uterus. The procedure can irritate the lining of your reproductive system temporarily. If you have sex too soon, you could develop pelvic inflammatory disease. After that waiting period, you can have sex anytime.
