Ok this is the very first post I've ever done anywhere so I thought maybe i could get some insight. I had my period for 1 day on day 26 (March 17th). It was heavy enough to use a super absorbancy tampon for the first part of the day. I noticed that the later part of the day it was lighter but i thought nothing of it. The next day, it was so light that i didn't even need to use a tampon, i just wore a pantiliner. I have taken 3 HPTs and they have all been negative. I don't have any symptoms other than being tired and getting slight waves of nausea. What do you guys think? My OBGYN told me to wait until april 1st to retest but i just don't know if it's normal to have a one day period. i haven't been under any stress either. Please help!!
