the cramping and bleeding is no good.
unfortunately if you go to a dr be prepared they may just say.. will have to wait and see.

but in saying this...

i have bright red / brown bleeding from week 3-6 which they called implanation bleeding. The dildo cam (internal u/s) at 6 weeks showed where i was still bleeding from the wall but bub and sac were fine.... ( i had no cramps thou)

the waiting game sucks and i hope all works out ok
