i didnt have morning sickness untill i was about 13 weeks, and mine stoped about 20 weeks. right now im about 28 weeks i think lol. but it gets better the further you get.
Morning sickness can last all your pregnancy for some....but normally it ends around your second trimester.....for me it didn't end until about 17/18 weeks :/......try drinking some ginger ale or some sour candies......I hope you feel better soon....also rest restt rest and drink lots of fluids.
Most people I've talked to have said that the sickness subsides around 12 weeks (end of first trimester). I'm only 5 weeks, and the only symptom I've had so far is tender breasts. Hope you feel better soon!
