Congrats on your BFP. I had a mc 2 weeks before my wedding back in 08. My husband was too afraid to try again until this year as he didn't want to lose another one. We were lucky and it worked the first month of trying. However even now I still worry about every twinge of pain or strange feeling I get, it's just natural.
A lot of people do have mc some before they even knew they were pregnant and still gone on to have a healthy 2nd pregnancy. I have been told that having 1 mc doesn't increase your risks of a second one, that's what I kept reminding myself in the early days.
(Sorry for long post, but I hope it helps put your mind at rest a bit)
