Ttc after miscarriage

I had a miscarriage on Saturday at 8 weeks. Only a week after seeing the heartbeat. Obviously it was an emotional time going through it and the bleeding is still continuing as I had a blood clot left (it was a completed miscarriage when I had the scan on monday). I haven't needed a d&c or anything, it's been a natural miscarriage.

This was my first pregnancy and although it was sad and emotional, I actually feel slight relief. They say 1 in 4 pregnancies result in miscarriage and it was always something I feared. I spent the whole 8 weeks obsessing over every little thing and googling every little twinge. So much so, I didn't really enjoy the pregnancy. I'm actually glad I've experienced it now because, as horrible as it was/is, I know what to expect and I know I can deal with it. I don't think I'm going to fear it as much in future pregnancies.

We're just wondering though, is there a rule to when you can start trying again? Obviously as my body hasn't finished bleeding we're not thinking now, but do we have to wait a cycle or can we try again when the bleedings stopped? Emotionally we're ok, it's the physical side we're waiting for.
