My period was 2 days late then it was spotting for two days and now nothing. I normally have 5-7 days heavy (heavy) periods. I normally use super plus and right now I don't even need a tampon. No it's not stress. I have been doing yoga but working out no matter how light or how hard the work outs are it never effects my periods they were always heavy. Also it's bright red/ pinkish color when I was spotting any thoughts?? Also I'm on birth control been on it for years.
