When to try again after a miscarriage?

1 week ago my symptoms faded and I "just knew" it wasn't good even though I grasped so tightly to all the positive posts on google saying symptoms come and go. 2 days ago I started spotting brown...again grasping to anything positive including my mom saying she spotted during her pregnancy randomly and it was nothing but deep down I knew.... I knew that at 6w1d there might be a heartbeat....hope....The brown turned to dark blood which then turned to bright red with clots...ultrasound yesterday confirmed nothing seen and my lining is thinning out. The nurse then took me to another waiting room just to have them tell me what I already know by the MD and get a pelvic exam. In the waiting room surrounded by happy glowing pregnant women at all stages of their pregnancy swooning over their ultrasound pictures and heartbeat recordings was the hardest moment and something I will never forget. I want so badly to feel the joy those mothers are feeling but instead I continue to bleed, bleed out the joy I once felt of a positive pregnancy test, sore breasts, fatigue and sensitive smells. My husband and I are sad but he's trying to be positive and make me laugh. The MD said wait one cycle before trying again but I know I've seen ladies on here who didn't... Just want advice.
