hi hun sounds like what i had at 7 weeks 6 days, cramping bleeding with clots! i went to EPU and they did scan me and told me all was ok, seeing a hb is in your favour im guessing it is a breakthrough bleed as your due your AF if wasnt pregnant they are very common, (which what i had) they can also make you bleed up to 16 weeks everytime your AF would be due, try take it easy and rest, sounding good your HCG is rising and ts very common these break through bleeds, its just i was explained when you hormones havent quite peeked to notifie the brain to not to bleed as your pregnant, it starts the process but once it realises your are acually pregnant it stops again that where the bleeding cramping etc comes into to, im hope your ok hun and gl x x x
