So...from my calculations AF isn't supposed to show until next week, although my body is whacked out these days.

Last night...
- Major cramps - I've never had cramps like this before, lower abdomen, excruciating
- Discharge that I normally get a couple of days before AF
- Spotting today

I'm trying not to stress. I don't know if it's AF, M/C or chemical because I've never experienced the latter two. What would you do??
