Morning sickness returns..?

Nothing serious.. But I had bad morning sickness around 5-10 weeks. Horrible nausea, upset stomach, couldn't eat or smell any type of food. Forced everyone to not even put left overs in my sight (not even fridge). My morning sickness came more later in the day and night time. It stopped completely at about 10 or 11 weeks and I just get indigestion and heartburn. Well I'm 17 weeks now and at about 15.5 or 16 weeks i started getting sick again. I'll get nauseous. Still later in the day and at night. When it comes to vomiting or almost vomiting its worse than it was in earlier pregnancy. Like, me and my hubby were at a Mexican restaurant, he stepped out to accept a phone call and when they brought our food I looked over and saw his burrito covered in quest and pico (makes me weak to type it!) and had to run to the bathroom to get sick. It never fails when we go out to eat. Since he's on leave, we have frequent nights out to dinner together, and I feel so bad when he puts thought and money into a nice place I LOVE but can't even keep down now..   Is it something I should mention to my midwife or dr? Would they be able to give me anything to help with it? Or do you know of some home remedies that could help?

It's normal for morning sickness to come and go. If it's really bothering you, you can ask your doctor for zofran.
