So a few days ago probably like 4 days when i went to use the bathroom i had a little bit of spotting i guess so when i wiped it was on the toilet paper and stuff with a blood clot like i was about to start my period so i got stuff ready and prepared but that was it like that one time and it was over so i didn't get my period but today when i got home from work i peed and it did the exact thing and I'm expected to get my period in 3 days i don't know what it was is this normal?
