Not to me it didn't. The stomach flu nausea should go away after a few days though. The pregnancy nausea stays a while longer.

I think it felt different. For me, the pregnancy nausea was very intense but seemed to originate in my head and throat. I had the constant urge to gag. However, my stomach actually felt fine. Throwing up did not make me feel better. Having and empty stomach makes pregnancy nausea much worse. With the stomach flu (viral gastroenteritis) your stomach and intestines hurt and are the source of your problems. Usually you feel better after you vomit. Not eating is the best thing you can do for the stomach flu. It is important to keep drinking and stay hydrated whatever you have. The best thing I have found to help pregnancy nausea are Preggie Pop Drops. They are amazing! You suck on them and it really helps your nausea immediately. They work because they contain glucose instead of sucrose (table sugar). Glucose requires no digestion. It is immediately absorbed and goes straight to your blood and brain. They are also made in flavors that are soothing to nauseated people. Also, the constant sucking and swallowing probably helps keep peristalsis going in the right direction. Preggie Pops are available at Motherhood Maternity and Babies R U. Or order them online. This is what you need to get for pregnancy nausea. I couldn't have gotten through the first trimester without them. No, I don't work for the company who makes them. http://www.threelollies.com/store/tek9.asp?pg=products&specific=jnrrnmo0
