The only symptoms I had when I was pregnant were nausea occasionally, not being able to eat certain foods, and for a week or two EXTREMELY sore breasts. I didn't have anything else. That pregnancy resulted in my now 20 month old son. So I wouldn't worry too much if you're not having a lot of symptoms, just consider yourself lucky. Try to relax and not stress, it's not good for you or baby.
i was never nausous. i had the easiest pregnancy an labor imagineable. every person is different and stress will only cause stress on the baby. so relax. take nice baths, get a massage, make love with your hubby. eveeything will be fine. if your extremely worried call the doctors ofice and tell hwm about the miscarriage history and that ur not feeling right. im sure thy would change ur appointment. and people cancel appointments all the time. calll daily and see if theres any open apptments
