Hi Izabella
I do not understand why your doctor did not just do a simple blood test which would tell you if you are pregnant. A HPT will come up positive if you are pregnant. It is a little unusual but yes you can have regular monthly bleeds when you are pregnant. These bleeds are usually not the same as your usually monthly cycle bleeds. Like others I also do not think that you are pregnant but I suggest that you go back to your doctor and ask for a blood test. This will help to ease your mind.
