The reason I'm worried is that this baby is usually extremely active - day and night. Far more so than my other two babies were. Although I'm only 21 weeks I have been able to feel movement from about 13 weeks and now I am used to reasonably strong kicks.
I feel guilty because last night I was lying on my tummy and I'm worried it did something bad (but it felt fine for me...)
I am waiting to hear back from the midwife's station. How worried would you be?
