Hi K1
I'm glad you have stopped bleeding. Thats one small hurdle over at least.
When to trying again for a baby is a completely individual choice, you must do whats right for you, so if you feel ready then that is not strange at all.
In terms of your cycle starting up again, I dont know if you can use the ERPC date or mc diagnosis but there is lots of info here about cycles starting up again. I personally counted ERPC date as Day 1 and expected a very odd cycle (it is affectionately known on MN as the WTF cycle
)
You should also read this about when its OK to have sex again, this says one week is too soon.
You can use Ovulation Predictor Kits (buy them on Amazon, much cheaper than at the pharmacy) to tell if you are ovulating (there is no guarantee though, it can be hit and miss) and take you temperature every day to know AFTER it has happened. See www.fertilityfriend.com, there are really great tutorials on here to explain how it works.
Before doing any of this though, I would recomend having a good read of this site, so that you can know what to expect about physical and emotional recovery

Sorry to have bombarded you with links!, take it slow, it will all be OK in the end.
a big hug for you,
