Oral Sex and Missed Period?
Can oral sex make you miss a period?
Oral sex will not make you miss a period. If you have also had unprotected intercourse and have missed a period, it is time to do a pregnancy test. Also, sexually transmitted infections can be transmitted through oral sex, so you might want to consider using a latex barrier (condoms or dental dam). If there are any open sores or cuts in your mouth, or if your gums are bleeding, you should avoid oral sex until everything heals.
