Trying Again After a Natural Miscarriage

K
I started spotting on September 1st before I even knew I was pregnant.  When I found out I was pregnant and went to the dr on the 3rd she said it was completely normal. I didn't find out that I was miscarrying until I switched to another obgyn after having multiple problems with my first. Today is the first day that I have not bled. My new dr suggested that we wait to try again until after my first period. I had planned on doing this since she said that it can help reduce stress and worry because she would have a menstrual cycle to base my due date off of. With this past pregnancy I was having regular periods so my first dr wasn't able to tell me how far along I was when I saw her. She said that I should expect a period within 3 weeks after I stopped bleeding but I really don't want to wait any longer before trying again. Is it safe to start trying? Has anyone else had a miscarriage and tried before their period?
