I'm so sorry for your loss. I've had 3 mc's in a row so I know exactly how you feel.
All I would say is try and wait for your first period so you give yourself time to recover and grieve. Trust me I know that knee jerk "I need to be pregnant NOW" feeling.
Waiting until your period will help your hormones rebalance and give you a starting point for dating a future pregnancy.
If you feel you can't wait, you MUST wait to get a negative pregnancy test before trying again.
Too many times I've seen the heartbreaking distress of women on these boards where they've desperately tried again straight away. Got a positive test and actually they aren't pregnant it's the hormones still in their body and they are heartbroken.
I got a bfn 1 week after my first mc, 2 weeks after my 2nd and took 4 weeks after my 3rd!!!! 
Please just take a deep breath, take a step back and just give yourself at least time to get a bfn before starting again.
I know it's hard but please remember every single pregnancy is genetically different. A new egg, new sperm, fresh lining. Your chances of a successful pregnancy next time are just as high as if you never had an mc.
I'm so sorry though. Please look after yourself
