Thanks for choosing health care magic for posting your query.
I understand from your description that you had an unprotected sex 2 weeks back. Then at that time you might have ruptured your hymen
. Its the emergency pill the progesterone
only pill that you had taken , might have led to hormonal
disturbances and the unexpected bleeding.
There is nothing wrong. The bleeding may last for some time and then stop. You will resume your regular periods.
In future use a condom and if you are planning to have sex regularly then start using OCPs.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
