Super light period!

A little tmi...period talk, obviously!

Every month I have always had a "normal" (for me) period. The first day was light..gradually for heavier, then light on the last day.

Last month I had 5 days of light spotting. Never had to use a tampon. I wore a panty liner and occasionally there would be a spot but not often.

Now the same thing this month. Just finished another 5 day "period" that was so light it was only ever pink when I wiped. Nothing on the panty liner except day 1, there was a spot the size of a pea maybe.

Anyone ever had this happen?

Just kinda curious as to why the heck the sudden change. Thanks ladies!!
