Hi Faith,
Ideally you need to wait until the test date to test as results can change as we can never predict exactly when implantation will take place. How heavy is the bleeding? Have you contacted the clinic as they may advise to increase your progesterone. I know its an incredibly anxious time right now but you are doing all you can. Definitely call the clinic so that they can offer some advice on the bleeding.
Take care,
