Every pregnancy is different, just as every woman. Never good to compare your pregnancies as they may have different symptoms.
Best advice? Ask your Dr for something. And drink water!! You should be drinking a gallon of water a day.
Good luck & congratulations!
Im on my second pregnancy also but my first was horrible. I was sick all 9 months. I lost 8 lbs my first trimester from not eating and vomiting. Drink a lot of fluids. I ate ginger snaps and drank Canada dry, supposedly is suppose to help. Nothing helped me to be honest. I got use to everything ttastin and smelling awful. Thes best advice I can give is to stay hydrated!
