That is an excellent question and one that should be addressed by your primary care doctor
, OB/GYN, or other emergency medical professional because based upon your history you provided, you may be having hemorrhaging which can become a medical emergency if not evaluated and treated in an urgent manner. The fact that you are developing clots is another red flag that suggests that you need to be evaluated in an urgent manner. There are several causes for this but in the face of continuing hemorrhage, the underlying causes are less important than the fact that you are evaluated because you can develop decreased blood counts which can cause other complications and injure organs within the body. When you go to the hospital, they will check your blood pressure and other vital signs, and if these are on the lower end, they may decide to give you a blood transfusion or fluid boluses to increase the amount of volume within the vessels in your body. They may also check a pregnancy test on you, check the clotting levels of your blood and other blood tests to elucidate the case of why this is happening.
