ADVICE PLEASE..Very upset about my loss.

Unfortunately I miscarried yesterday . I'm very devastated. Started spotting brown which I took as a sign of old blood which is normal. Then it started coming and getting brighter which I took as a sign of possible miscarry. I went to the ER They said everything looked fine cervix was still closed and baby was still there. The next morning I experience cramping and back pains then passed what I took at the baby a big clot and a pink looking almost white sac. I showed my husband and he always sees the good in everything. He says and I quote "baby, stop stressing its ok the Baby will be fine". I just knew, the whole mothers intuition hit me hard. I called my OB this morning and went in. She did an ultrasound again and she said im sorry but the sac is gone you miscarried. I broke down. I really wanted this to be it. I know my baby is in heaven enjoying its small little life but I really wished I had the chance to kiss my babies face. I was 8 weeks. We aren't giving up but I don't think I can emotionally take another heart ache like the one I experienced today! I wish you all the best just wanted to share my story and ask how long should I wait to try again, thats If i decide to try again? My ob said the wait 3 cycles is a hoax but didn't tell me how long or even if I should wait? Any advice?
