Is this always true to every pregnant woman? If so, then should an expecting pregnant mother should be looking for this sign?

I know that the changes of the body of a pregnant woman makes her vomit. I would like to know how does it happen?

I never knew the why of it, but I also know that it isn't always that way. I had 4 kids and each time the morning sickness was less.The last pregnancy ,I never vomited at all.So that is not always a sure sign.I do know every pregnancy is different so would be the signs.:rolleyes: Hope this helps answer some of your questions.

I think I agree in this ...

I didn't get pregnant yet, but I discussed with many women I know. Some claim they didn't vomit at all and the morning sickness wasn't present in their case. Of course, some had these a lot, poor girls.

I would consider the delay in the menstrual cycle to be the first sign, especially if it's regulated ... And of course the tests and the medical examination are the ones to confirm the presence of pregnancy

Not everyone has morning sickness, and especially with all the cases of flu and food contamination lately its just as likely not pregnancy these days. While it could be a sign, its not conclusive at all.

Pregnancy symtoms are just as vast and individual as people are. I only actually 'threw up' twice with the first, and then no more with others. I did however 'feel sick'' for a couple of months. I think I have more nausa now then when I was pregnant! ha ha

The only thing all my pregnancies had in common was that I had no periods. I had sore breats with some,morning sickness with one ,One I just felt tired for like the first 4 months.So I would say the first sure fire way would be that you miss your period, although I have heard of women who have a light period even.They say you can take the in home pregnancy test as soon as you are 1 day late.:eek:

So this means that throwing up could be a sign of being pregnant but not totally a look-out for ladies wanting to have a baby. I mean it can be sign but will not always happen.

Ok, now I know that vomiting is not a general sign for getting pregnant. But how why does it happen?
