OK I'm one of the ones where it ended quite abruptly at 17 weeks. The cause was preterm labour after the repeat bleeding weakening the membranes. I'm not too sure of this because I went on to have another pregnancy that had no bleeding but my membranes broke again due to incomp cervix. I had bleeding that TMI drained throug clothes into puddles in a matter of seconds with no warning I think it was a large haematoma tho. I think it all depends on the individual preg I hope you all have a wonderful h&h pregnancy
