Again?

3 cycles past my loss and I'm pregnant again. It's what I want and still I'm fearful. I don't want to give the exact fears description less that become reality. In the weeks that followed my anatomy scan and D&E, I was so certain I wanted a third baby, I wanted my lost one back, and because that was impossible, I wanted to try again. I was fearful that Hubs would say no, the lost one was an 'oops baby' after all. But, my fears in that direction were thankfully unfounded. Hubs was willing to go in whatever procreative direction I wished to go. So here I am, in my 5th pregnancy, with only 2 living children. When I'm not crying, I'm numb. I got my positive home pregnancy test this past Wed/Thurs, but have not yet contacted my healthcare professional. I've never dealt with chemical pregnancies and yet I fear this will become that. I have dealt with missed miscarriages, an early and a 2nd trimester. When I can momentarily feel excited and happy, I'm nearly breathless with anticipation.
I still feel wrong in posting this information online in any fashion, I'm convinced I'm jinxing myself, although past experience tells me I'm being silly.
