I'm sorry you have to go through this.
The bleeding was around a week. Should be typical with a regular delivery. As for waiting to try again, physically I would wait until after your follow up dr. appt. and/or your next cycle. So 4 - 6 weeks.
As for being emotionally ready, that is a different story. For me it took a few months, and then I just felt like being held. Each person is different. Even your hubby will be different. That was hard for me to understand that hubby was ready to move on before I was.
In the end, I ended up pregnant about 4m after the miscarriage. I was completely stressed through the whole pregnancy, but was able to carry to term.
If people are offended that you hadn't told them about the pregnancy, just play it off. My hubby had gone and told the world when we found out, but then told no one when we lost it. It was very odd for me when friends would come up congratulating me. By that time I was pregnant again, so I played it off. For the after pregnancy, we didn't tell anyone except for the grandparents, and swore them to secrecy, until after the 1st trimester. We had a big family birthday party coming up then, and timed the announcement with that.
Hugs.
