Dear thanks for the question. Firstly your details are not complete. Date of last menstrual period is most important to diagnose pregnancy. However the details you have provided do not indicate pregnancy. Fluid in pouch of Douglas is outside the uterus. There is no relation between sore breast and pregnancy. Colour of discharge is also not relevant, it is time since last menstrual discharge which is required. Increased hunger is observed in advance pregnancy, not in beginning. In beginning you have nausea and vomiting , that reduces hunger. Constantly sleeping is also not related to pregnancy. You need to visit a gynaecologist and surgeon (depending on gynaecologist advise) to identify the cause of fluid in pouch of Douglas as it indicates some problem in abdomen. I hope my answer will benefit you. Please write for follow up queries. Kindly rate the reply. I wish you good health. Thank you
