JayJay - I just thought i'd mention that a gf of mine had bleeding very similar to yours.. It was happening quite frequently though and lots of blood, but baby was fine. It ended up being - to my understanding - her placenta was over her cervix and was causing the blood loss. She was in and out of hospital due to copious amounts of blood loss, however she went on to have her son, via c section and earlier than usual because apparently the blood loss in the end was dangerous to her and the baby. But in the end she had a perfect little boy I hope you find an answer at your MW appointment. Goodluck and wishing you a happy and healthy pregnancy!
