My periods returned 4 months ago after I stopped breastfeeding. All was fine. Same length as used to be and always on time. I have been to the doctor for a general post birth check up. All was fine as well. Ultrasound, blood test. All good. Now I have been menstruating for 2 full weeks instead of usual 5-6 d. No pains but the blood is bright and it doesn't seem to stop at all. AIBU to be a bit worried? It is not much blood so I cannot really call it a bleeding but still...
