URGENT, PLEASE

Patient: My girlfriend and I are worried, since we don’t know if she can be pregnant. She is taking since a couple of months contraceptives, for her skin. We had sex two weeks ago without any other protection, she has her period three days later, also three days before the normal day. Since then she has been having brown vaginal discharges every day, for one week. Could it be pregnancy? Or an infection?

Symptoms: brown vaginal discharges
contraceptics taken

Doctor:
