WARNING.. Loooong Story (My Story)

Beth
I'm currently going through the end of my miscarriage.. I thought I was 9 weeks but the sac was measuring 4 weeks and no yolk or baby. It is our first pregnancy and was so heartbreaking! I started bleeding last Friday and passed what was believed to be the 'sac' wednesday so hoping the bleeding should stop soon! I had blood tests Tuesday (levels 3300) and more yesterday, Thursday (levels 810) so they dropped significantly! I have to have more blood tests in a week and hoping they will be back to normal by then.. 
To add to our heart break, my OH great nan passed away this morning, so I will be glad to see the back of this week, it's felt like the world is against us!! We are both desperate to try again as soon as possible.. The midwife I saw for the scan last week advised me to wait at least till I get 1 AF before trying again, I've read people are told to wait 2-3 cycles.. I've seen some people don't get their AF for like 8 weeks after miscarriage (which seems like a lifetime and I'm not sure I can wait that long).. I've also seen that people were told they can try again as soon as the bleeding stops and that they only say to wait 1 AF for dating! I would love to start again right away as I'm so impatient and miss the idea of being pregnant, but don't want to cause problems to my body!! I would just love some of your advise and experiences.. How you felt? What you were advised etc? I'm just so desperate to have a baby and its hard seeing friends and family announcing pregnancies and having babies, just rubs salt in the wounds.. I'm feeling 100% ready to try again. I believe everything happens for a reason and I understand that my miscarriage was nothing to do with anything I did or didn't do, my body is helping me, not going against me as my baby just wasn't quite perfect this time! 
Sorry for the essay, I just thought I would explain the whole story! (I did warn you it was long).. Thank you all in advance ladies, hope your all staying strong through your hard times too, sending all my love and best wishes!!! 💕
