<s>[INST] Hello, I am 30 year old married women. my period is due on 16th of this month. my peiod is always coming 4-5 day before it time. we are trying for baby for last 3-4 months. This month my period comes on 9th of this month with very thicky dark red bleeding not continuously and last long upto today. I am confuse that that is my regular period or not. please guide me. what is a sign of it. [/INST] Welcome to Chat Doctor Good Davits possible this is hemorrhagic if the volume of bleeding was more than always. Is the bleeding painless or painful. Are you on any medication? Painless bleeding could indicate it is non-ovulatory bleeding. Any back pain. You need to get examined by the Gynecologist to rule out endometrial thickening and other causes which may be the reason of this sort of bleeding. An Ultrasound will help as well to rule out fibroid, endometriosis etc. Kindly get evaluated by your Doctor as soon as possible. </s>
