I got up this morning and felt like I had a stomach ache, then it went away, I felt fine ate 2 tangerines and had coffee, then all of a sudden I had a horrible naseau, went and threw up twice and still feel pretty bad, anyone had a return of Naseau around twenty weeks? Anyone know if it's cause of a growth spurt or just normal pregnancy hormones ? Just want to see if anyone is experiencing the same thing !
