Daughter's extremely light periods

[Nathalie1975]

My DD(12) started her periods about 10 months ago. Her periods have been reasonably regular (every 22 to 35 days) but they are extremely light, more like spotting. She says mostly brown with only a bit of red sometimes and only a small amount in a pad after a whole day. They last about 4 days. I was wondering how usual/unusual that is and if I should be worried.
I have PCOS myself but it presented very differently ( first periods very heavy followed by very infrequent periods).

I wouldn't worry about it, the PCOS criteria is Irregular periods, shorter ones or missed ones, so 4/5 days which are light don't really fit that mark. Also at 12 periods take a while to settle, so more time is needed to think about the 22-35 days period. Just watch how it goes. As you know she'd also either need certain hormones to be high and/or lots of small follicles, and/or irregular/short/missed periods to qualify for the 2 out of 3 symptoms of PCOS. If they aren't bothering her too much, just see if anything changes.

Thank you. I think I am a bit paranoid because I had fertility issues and my biggest fear is that I passed it on to DD. Also, there's a lot of info online about heavy periods but very little about light periods.
