trying to conceive and miscarriage

My husband and I have been trying to concieve for almost three years and when we finally got pregnant last month I had a miscarriage which my dr. sees as no problem however I disagree after three years you'd think this might be a sign of needing to intervene. The next unpleasantry from this is that every person I see wants to know when are you going to have a brother or sister for your son. I just want to scraem and the best is when everybody was like oh are you pregant yet and I was going through the miscarriage and my all time favorite is well now your body will be ready to get pregnant faster or at least you know you can get pregnant now. I don't believe that people can just diregard the baby that easily and my husband and my feelings. Any advice from anyone or any luck with fertlity monitors. I have had it with charts and temps and planning everything for the right time my husband even jokes now that he's on aschedule and I think that maybe the monitor would reassure me that we are in fact at least trying at the right time. Best of luck to all of you and any advice would be greatly appreciated. Thanks
