@Bao: I felt like this, pretty much identically to what Miss-Spunkin described. I found out I was pregnant two days before the last Harry Potter movie came out, and I was having mild cramping, so I remember sitting through the movie in blind terror because I was so sure I was going to miscarry.
It took a long, LONG time to ease it, and while it’s better now, every time I hear a story about a baby being lost during late pregnancy, it flares up again.
I worried so much I had a lot of difficulty becoming attached to her. I would go into ultrasounds and expect to hear that something had gone wrong, and she wasn’t alive anymore. It was stressful for me, and for Darling Husband, and probably not great for the baby either.
And, like you, I had no reason to worry, which makes me think it comes with the territory, and I was unprepared for it, so it blindsided me like a big old truck.
Focus on the good things about your pregnancy, make lists of baby names, get nursery inspiration boards together. Start doing research on cloth/regular diapering, or breast/formula feeding, whatever. Anything to keep you actively engaged in bonding with your baby, because, worrying doesn’t change it anyway. I missed a lot of my pregnancy thinking she was going to die, and I’m sorry about it now.
Also, my Morning Sickness was almost identical to Miss-Spunkin’s, it started like 6-7 weeks and lasted well into the second trimester. I STILL throw up (29 weeks) every now and again. It’s reassuring that you have it for like a day. After that you just pray for it to go away, and it feels like a long LONG time before it does. I cried more over feeling so sick than I did over ANYTHING else about this pregnancy so far, and basically didn’t leave the house for four months. Just trust me, you don’t want it!
