I tried googling it, but all I got was "I got this when I was pregnant!" and "I'm definitely not pregnant, so why is this happening?" with no actual answers. My period is due today (or was due yesterday, can't remember) and I have been having my usual bout of supernatural pregnancy anxiety (never had sex with a penis involved that I can remember, yet this doesn't stop me freaking out!), but all that aside, has anyone else felt this? Did you ever find out what the cause was?
Doubt it makes a difference, but, no birth control, and not approaching menopause (I don't think; I'm 29, and my hormone levels tested "normal" this time last month), which seems to be a common factor in the non-pregnant folks who've experienced this.
