I woke up in the morning really exited because I was going to my friends house, so I woke up and went into my mums room for a while and when I woke up again I kinda was just walking around the house when I sneezed, I thought it was like discharge so went to the bathroom to wipe it because ew, anyway, on my underwear there was a brown spot and when I wiped it was brown, I don’t really know if was my period or not, please help !!
