First of all, it's totally normal to feel nervous about another pregnancy if you've had a loss. It makes you hyper-aware too of your symptoms and any loss of them. But it's also important to know that stress and anxiety can mask pg symptoms, and make it seem like they've disappeared. Another possible reason is that symptoms can go away around this time because your hormones aren't sky-rocketing up anymore. If you look at an hCG graph, they typically start leveling off around 9 weeks and because your hormones aren't jumping drastically anymore, your body adjusts. So symptom loss isn't a for sure sign that your pregnancy is ending. One other note, not all women have symptoms daily and some don't have any at all. I know it's hard to think positively right now (believe me, I know. I've had several losses and my successful pregnancies have nearly all started with bleeding in the first tri.) but it's really all you can do. Try to relax as best you can and just take it easy. Statistically, if you've heard a heartbeat, the risk of miscarrying drops drastically. Yes, it's still possible to have a loss but the likelihood is considerably lessened. (Like less than 5% or something.) Hang in there. Do you have a doctor's appt coming up or an ultrasound scheduled? If not, maybe you could call your dr about having some blood tests done to make sure your hormones are still rising like they should or schedule an ultrasound for your peace of mind. My dr is great for getting me in whenever I feel I need to and it really does help get me through those panicky first months.
