i would definately go back you are not fussing, you want to be sure hat is going on, just tell your doctor what you have told us, how much bleeding well spotting you had, your symptoms now and your test. Ihave had 5 miscarraiges and even the really early ones that were a few days after af was due, i bled just a bt heavier than a period, it starte off brown but then went to full blown bright red.
