Out of left field 2nd trimester vomiting

What in the world is going on? I managed to get to 18.5 weeks with mild nausea but I never have actually thrown up. I haven't felt sick at all for a good 3-4 weeks now. Well, on Saturday I began feeling queasy and was in bed all day long. I could not get comfortable or sleep.

Finally around 11:30 I threw up. Ugh that was awful. I woke up Sun morning starving so I thought I must have just eaten something bad. I had a big breakfast and felt good through the afternoon. I started feeling icky again last night and then woke up this morning feeling very queasy. I tried to eat a bagel and got about half down. Well, that came back up at about noon.

So, I called my midwife and asked her advice. She said most likely it is the baby pushing the intestines and stomach out of the way. In the past week I have really been feeling her kick and move alot so I gues she is using me as a punching bad and I my body is not liking it too much.

I can't complain too much since I absolutely love feeling her move. But this was totally unexpected. I thought the nausea part was past. I guess I had to puke at least once during the pregnancy right??? What other great suprises am I in store for?
