I lost a baby before having my dd, and my first trimester with dd was so hard. I think I checked for blood every single time I went to the bathroom. One day all of my pg symptoms (m/s, fatigue, etc.) completely disappeared. I
freaked out. The same day I found out the previous pg was not viable, all of my symptoms totally went away too. So I was so afraid I was going to lose my dd too. But the next day everything was back with full force, and you can see pictures of her in my siggy -- happy and healthy

.
I don't think there really is a magic way to get over your fears. The risk of m/c is very real and it is sadly quite common. Life is what it is, and we have no control over things. The thing I try to practice day in and day out is surrender. But it is a practice, and something that is often easier said than done. I've been working on it pretty hard for the last two years (dd's birth led me down an incredible path of healing), so I do mostly feel a sense of peace this time around, and am not as worried as before. It is what it is. But it's taken a lot of time, and a lot of hard work to get to where I'm at, and I certainly don't feel that way all the time

. It's also made easier by the fact that we don't seem to have any trouble getting pg. I'm sure I would be much more fearful if we had been battling fertility issues.
I just try as best I can to enjoy each day, and take them a day at a time. I really like what Aimee said: "but I thought if I *do* lose this baby I want his 8 weeks on earth to be beautiful, not stress filled and wrought with tension."
