Okay, let me start off with saying that I'm skeptical because of what I've read, thus far, when it comes to ovulation and such.

I had a period start on Feb. 17th, and it was an average one. I had another one start around the 5th of March. I know what triggered this... Stress. It's never happened before, though.. Normally, it is late due to stress.

Approximately 2 and a half weeks ago, (only a few days after my period had ended) I ran a fever for 3 days. I was not sick, this I know for sure. I know, or at least I think I know, how my body warms up, during the fertile time.
Could my cycle have been completely thrown off, and I ovulated during the time of the fever?

I feel some awkward changes occurring in my body. I understand, it's "too soon" to tell, according to a lot of people.
Allow me to quickly list what's been happening...

Exhausted.. I can't sleep enough.
Odd .. cramping, but not quite cramping. It's not painful, but it's something. Almost a 'full' feeling? Similar to premenstrual, but different.
Very faint queasy feeling, for most of the day.. sometimes becomes stronger.

This has been going on for about a week, give or take a couple days. Personally, I feel it's too soon to tell anything, but I was looking up the odd 'cramping' during the beginning of the week, and kept coming across pregnancy.. It seems to be what my mind is on, too. Not that I want to be.. Not in the position to be a mother, right now, so I don't believe it's conjured up, like a lot of females tend to do.

Well, I've been trying to shrug this off, saying I'm not... Until tonight, when I wanted to vomit each time I smelled cigar smoke, at the bowling alley. That smell has never, ever bothered me.
As well, twice tonight, when I used the restroom, I discovered a brownish/pinkish discharge.

So, any idea as to what's going on, here?
Thanks for your time.
