At 9w5d (assumed by your due date!), your chance of your pregnancy being viable is 98%. Your chance of viability, which is already really great, will raise to over 99% by 13 weeks along, so it steadily goes up a little bit every single day. You could miscarry a healthy fetus, but that's really, really rare. If your body decides to let go of the pregnancy, it is most likely because the fetus is NOT healthy enough to have a good quality of life on the outside, and it's trying to spare both of you a lot of pain and suffering (although that would be very difficult to go through no matter what). I have had blood-streaked CM and spotting during the first half of all of my subsequent pregnancies. It's scary, but I think once you've had a baby, your chances of spotting go up, and your chances of spotting goes up (and your chance of a healthy baby goes up) with each successful pregnancy. I am a worrier, but being on the outside of this situation, I can see it much more clearly than if I were in your shoes, and I find it pretty easy to tell you that you probably don't need to worry at this point. It's all common, and it's all right. Definitely avoid BDing until all bleeding/spotting has stopped, and then maybe avoid it for a little longer to let your sensitive cervix harden up a bit. I find that around 15 weeks, my cervix stops being so sensitive, so it can take a lot more abuse then - ha! But sex makes me bleed until that point, so I really don't have penetrative sex until I get to that point, and I definitely try to avoid having to push for BMs because that gets me bleeding, too.
