Isn't this the best time to be sick?

I am sick, I feel like there is a war going on in my stomach and I have gone to the bathroom to throw up more times than I can count (that's a nice thing to write about hun?). Of course I haven't actually thrown up yet which is why I am not feeling any better.
Now why, you ask, is this such a (insert sarcastic tone) good time to be sick? .... Because I am due to have my period in a couple of days!!!
I know I probably just ate something (I even know it was the dozens of chestnuts I ate last night) but I can't help thinking, in the back of my mind, what if this is a symptom?
