My period has always been for 7 days, no questions asked. This time it was a day late and only lasted for 2 and ahalf days, then on third and fourth day just small amount of brown discharge. I have period type cramps in my lower abd but no bleeding. Not sure if I have been peeing more, I kinda think so. My breast were sore before I started but not anymore. It seems like my nipples are kinda sore though. Took a test the day my period was due and it was neg. Trying to keep up with ovulation but could I have miscalculated and really be pregnant? %-)
