Why do I experience bleeding after sex with no pain or discomfort?

Yes it is best to see a gynae for some blood tests and a pelvic ultrasound. Prolonged heavy menses may result in iron deficiency anemia, and this needs to be corrected. Issues which need to be excluded include any gynaecological problems like fibroids or endometrial polyps, as well as any problems with blood clotting. Even if all is normal on testing, heavy periods are not something you have to put up with with.

One day is pretty quick for the symptoms you’ve described to appear – so I’m going to work with the assumption that this is not the first time you’ve gone for unprotected oral sex. You have clearly exposed yourself by having unprotected oral sex, so you need to go to an STD clinic ASAP for a screening check-up. If you had sex with your partner after having unprotected oral sex, she should also be screened. It’s important that you do so – STDs can be passed on to your partner and baby as well, if they are not treated.
