First of all, relax. Panic makes everything worse. And many times things look worse than they are and fear becomes our driving force.
Three things come to mind. Because of your message, I would guess that there is a hormone imbalance. My second guess would be fibroid tumors. How heavy is the flow? With fibroid tumors the flow can tend to be quite heavy and if this is the case you need to be careful. And my third guess is endomitriosis.
However, without the blood test results it is impossible to tell. Once you get the blood test results that should let you know what you are dealing with.
There are natural ways to deal with these conditions. Let me know what the test results show. Are you on any medications?
In case I should miss your reply, I can be found in the Ask Tony Isaacs Forum. Please feel free to ask any questions and if I do not know the answer, I will find out for you. Right now we need to know what we are dealing with.
First and foremost though, you must calm down. Anxiety will not help and most likely your condition will be dealt with successfully. If your blood flow is heavy and you are feeling weak call your health care provider. I always recommend a naturopath. However, if you need immediate help, by all means contact your health provider. And of course if you are having a heavy blood flow, relax and take it easy. Don't do anything strenuous, no lifting, etc.
For now, relax, put it out of your mind and when you get your blood test results we will go from there. Let me know regardless, even if it shows normal.
Hugs,
