I'm at 15 weeks but still occasionally throwing up, at various unpredictable hours of the afternoon and night. It's uncomfortable when it happens, but my food aversions have gone away, so on the whole I feel much better than I did in 1st trimester. And I made it up till yesterday without ever throwing up at work!
But yesterday afternoon at work I started feeling really sick all of a sudden. I rushed out of my office to throw up in the bathroom but ran into two coworkers who were chatting in a common area. I haven't told anyone at work that I am pregnant and I have no plans to do so until I absolutely can't hide the bump. (Hoping to make it till early March without telling!) My face was bright red as a weird side effect of the nausea and I must have looked really bad.
When I came out of the bathroom they asked what was wrong, and I just blurted out that I was having an allergic reaction to an apple I ate! Ha ha. Oddest fib ever, but they seemed to buy it.
Maybe someday I'll tell them it wasn't really an apple... :)
