Yesterday I hit the 12 w! The weird thing is all pregnancy symptoms has started a week ago and now uprising! First time I vomit today! I have incredible indigestion, burping all the time! Heartburn!!! As far as I know, it suppose to be on the otherway around. Am I wrong? Is any one has an experience like that? By the way I stop estradiol last week, and decrease the progestron doose, can it be a side effect?
