This bleeding can be due to intermenstrual bleeding. Main causes of spotting between periods could be due to pregnancy, birth control pills, infection in an area of the body related to menstruation (including the vagina, the cervix and even the bladder). Other causes could be polycystic ovarian syndrome, diseases of pituitary gland, hormonal imbalance of estrogen and progesterone and uterine abnormalities like fibroid and cervical dysplasia. Your doctor may consider tests like blood sugar levels, thyroid function test, prolactin, follicle-stimulating hormone (FSA), estrogen, and testosterone. Imaging studies, such as ultrasound, X-ray, and CT scan may also be recommended in certain individuals.

Thank you so much for your reply.
I have seen my doctor yesterday and he was not concerned about it. He did however, make me a requisition to get a pelvic ultrasound done.
I asked him if it is maybe endometriosis or cysts but he said he doesn't think so.
My ultrasound is on april 10, I will post back here about the results.
