My wife is around 8-9 weeks pregnant. We had 2 miscarriages last year and she is worrying a lot this time although trying not too. She gets anxious when her nausea settles and worries the baby has died. It changes day to day so I can't really identify a pattern but today she is worried as she doesn't really feel sick although she did this morning for a while. Can anyone help - is this changing patterns of sickness OK? I can't reassure her a s I really don't know.

Morning sickness doesn't really follow a pattern. It may calm her fears however, to know that around 56% of women experience it at some point.

It is no indication that your baby is in trouble.
Has she picked up the book, "What to Expect While You're Expecting" ? I highly recommend it.

Having a couple days here and there with no morning sickness is something to be thankful about. I completely understand the fears, but more than likely it is completely normal. If she is concerned about anything for any reason she can always call her doctor and discuss with them. Congrats on the pregnancy!

Morning sickness is actually brought on by fluctuating/low blood sugar levels. This is why it is referred to as morning sickness(even though it can occure at any time of the day) because your blood sugar is typically lower when you wake up in the morning, having not eaten all night long. So based on that, you could understand how the sickness would come and go.

Morning sickness is caused by the rise of hCG in her system. HCG rises during the first 12 weeks of pregnancy when it begins to fall again. This is why after the first 12 weeks (3 months) women have less or no morning sickness.

Many women do not even experience morning sickness at all.

The level of morning sickness has nothing to do with the health of the baby. Tell her not to worry, it should go away completely here soon, and she can still deliver a healthy baby.

It seems she has some misconceptions about pregnancy, it may be good for her to talk to her doctor about her fears and any questions she may have so that she does not fret for the rest of the pregnancy.
