MC 4/26/14. When to ttc again. (Tmi)

I miscarried on the 26th April. I bled heavy with (tmi) lots of clotting for 5 full days and the bleeding was heavy everyday. 
I started spotting brown blood on Thursday 29th may and got full red flow on Saturday 31st with bleeding still on Sunday 1st June Today 2nd June the bleeding has slowed back to reddish brown when I wipe and only slightly on the pad. It's been 34days since I miscarried. Do you think it will be okay to start trying again now that I have my period? 
I really don't know what to do. Hcg still in my system as I am still testing positive on pg tests. So this will affect my opk's too. So I won't know when I am oving. How long did you ladies that have had the agonising ordeal of going through a miscarriage wait till you started to ttc again? My doctors have been rubbish I am in the process of changing. 
​I want a baby so much more now that I have lost my first baby.
