Hi, and thanks for your medical question on eHealth forum!
Discharge and blood on 14th day of cycle can be due to ovulation. However, if the period on 25th was unduly light, then yes, possibility of pregnancy, tubal or normal is there. The only way to confirm is take blood HCG tests 48 hours apart, and if the HCG levels are rising, then you are pregnant. Since a confirmed diagnosis cannot be given on net please consult your gynecologist regarding this. Hope this helps. Take care!
