For those spotting/bleeding, here's a quote I found on the Berkley Parent?s Website :
"Hi Becky,
It's scary isn't it? I started bleeding around my third week and continued pretty consistently (and heavily) until my 11th or so. I did two ultrasounds and in both cases the embryo/fetus/baby was viable. I am now into my 15th week and am no longer bleeding -- big sigh or relief.
No Western medicine doctor had an explanation, though an ultrasound tech said that she thought I had little bubbles of blood that were bursting, like air bubbles under wallpaper. My acupuncturist said I had old, stagnant blood in my uterus and this was my body's way of clearing it out to make room for the baby. So, no definitive ''this is why you're bleeding.''
From what I read, 1 out 4 women have bleeding and many go on to carry the child full-term. Guess it's just one of those things they don't tell you about pregnancy. Obviously, I'd suggest continuing to check and make sure everything is okay, but otherwise...well, for me, it was about waiting it out.
Good luck! and best wishes! Ericka"
