Hi Psycobear- So sorry for what you are going through, hoping you're one of the lucky ones who can have a healthy pg after bleeding (lots of ladies do).
As for my own experience - with my second MC, I began spotting very lightly at about the 6 week mark, it was light brown, painless and Very very light. This continued for 2 weeks, and at no time did I have any pain, or bleed heavy enough to soak a pad (sorry if TMI). Till this point, I hadnt even seen a doctor as 1. I was hoping it was nothing and was still getting + HPTs 2. I figured if I was Mcing there was nothing they'd be able to do to stop it.
After 2 weeks of this, I woke in the night with the most excruciating cramps. I literally thought I was going to die. Stupidly put up with it till morning then went to the dr who confirmed that I had MC'd. Was devastated, but surprised because of the HPTs, as at that time I didnt jnow that HCG levels go back down gradually. Anyway, moral of my story was that if Id gone to the dr earlier, I wouldve probably had a DC and saved the pain, and this experience has made me fairly suspicious of any prolonged bleeding. Sorry about the crappy ending.I know this isnt what you want to hear right now, and I truly hope in all my heart that it wont be the case with you. Take care.
