Hi, My girl friend is 24 years old and healthy. She is normally having regular periods. But recently since we started ahaving sex, she is usually getting her peiods 3-7 days late from expected 28 days. This month her periods started on 9th as expected but again she started bleeding after 11 days which lasted for 3 days. She is also having some white descahreg intermittently.
Can you please guide what could bepossible cause?
