Why do I have morning sickness? Will this last my entire pregnancy or is there anything I can do about it?

Morning sickness is frequently a problem with pregnancy.  Fortunately, most of the time it is relatively short term and generally occurs between 8-14 weeks into the pregnancy.  Some women do have morning sickness throughout the entire pregnancy, but most do not.  There are medications to help with this if necessary.  On the good side, morning sickness is associated with a high pregnancy hormone level which is usually associated with a good outcome for the pregnancy.
