Hi, The hospital advised wait for one AF- but like the other girls say, think that more for dating purposes. Think it depends on if you are emotionally ready for another pregnancy? GP said give it a couple months to get stronger.
Following my MMC 8/2/10, We decided to wait, I just felt better knowing that my body had got back to "Normal" if you like and had my first "oil change"! Having said that I have just had first AF, but when it came to it, I realise I am still raw emotionally, not ready, so will review the situation maybe next month.
If you are ready, then Good luck x
