Hi, thanks for the question.
How long will the bleeding last after first penetration?
Normally it will last for a few hours after the first penetration due to trauma of the hymen, but it depends on the elasticity of the hymen.
In your case, if I’m not mistaken, you have been bleeding for the past 2 days but you had sex a week ago. Usually this bleeding isn’t causing by the broken hymen.
Bleeding and pain is normal after first penetration
The pain should be reduced by the third time you have sexual activity.
Withdrawal method and pregnancy
There are a lot of methods to prevent unwanted pregnancy. The method which you used (the "pull out" method) is less reliable. Statistics says the effectiveness of this particular method is around 73% when it is properly performed.
However, I will suggest for you to use condoms everytime you have sex for your own protection, because it can prevent you from sexual transmitted disease too. Additionally, don’t forget to track your period if you’re sexually active.
Which doctor should you see if you are still experiencing bleeding problems
General Practitioners can help you investigate the cause behind your pain and bleeding.
If the bleeding is severe (measured by how many times you have to change your pads/tampons a day) and it lasts more than a week, you should see a Gynaecologist.
If you want to take a pregnancy test on your own, I'd suggest for you to do it at least 2 weeks after you had unprotected sex.
