Fear and anxiety

Sarah • My husband and I have been together 12 years. We have one son who is 6 and we have been trying to conceive for 3 years now.
I miscarried yesterday. I'm still bleeding but the Dr thinks all the tissue expelled naturally. I'm nervous about trying again but I've heard that you could be more fertile after a mc. I don't want to not try and not get pregnant later on and look back and wonder if I had a chance. I also don't want to try again so soon and get pregnant and have another mc. Any insights? How long did you wait till you started trying again after a mc? Any insight is helpful.
