Menstrual Color: Things Your Period Blood Color Says About Your Health

Did you know that your period can be the biggest and clearest window to what is going on inside your body?

During menstruation, women may experience blood of different colors. Sometimes, the blood may be bright red, while other times it may be a deep red or brownish color.

Period blood is actually the tissue that builds up to line our uteruses each month.

Read on and find out, you master of menstruation, you.

Brown/Very Dark Red

This happens when periods start slowly, with a light flow that becomes heavier as the week goes on.

During those light flow days, the blood takes longer to exit your body, and takes on a darker color as it makes its slow exit.

Thus, we end up with some "leftover" uterine lining that carries over into our next cycle. But it's totally healthy and normal, and nothing to be nervous about.

Bright Red/Pink

Bright red period is your newer uterine lining, so that's why it often follows the expulsion of "old" dark lining in your cycle. It's also why a heavy period might be bright red, the blood is flowing out of your body very quickly, and does not have the time to darken.

Some folks have bright red blood throughout their whole crimson tide, and there's nothing wrong with that.

Cranberry/Medium Red

This is a perfectly healthy color to get in the middle of your period. Some folks — especially those of us who have longer periods — expel our uterine lining at an overall slower rate, and so our periods take on a consistently darker color, and never switch over to bright red.


This is the only color that should cause alarm if you see it in your panties. Gray clumps or discharge during or before your period may mean that you have an infection or that you may be having a miscarriage.

It's a good idea to call your gyno if you see gray discharge, even if you can't imagine how you could have gotten an infection or pregnant.
