i had a period may 7th. it was maybe 2 days late. then fast forward 16 days and the first 3 1/2 days were light to where i only had to wear panty liners.but the last couple of days i had to wear a regular tampon( that's all i had left). but even then those weren't getting filled . today it went back down to being light.my next period is 8 days away. ive only spotted once between periods and that was in February. and that was really light compared to this. I'm not on any birth control, medication, no new life style change, no New diet....anybody else go through this? and what was the outcome? any idea what could be going on?
