Weird light periods

Hi all-

Was wondering if any of you had issues with your periods becoming light and long due to stress?

Or does stress usually make them heavy or irregularly timed?

Last 2 month they have mostly just been spotting for a few days, then 1-2 days of a very light period and then several more days spotting. Still at a normal time pretty much.

So frustrating! After the first month or randomness I started Vitex, red raspberry tea, myo-inositol, L-arginine and vitamin E (besides a Prenatal and folic acid of course) and honestly is seems worse!

PCos or just stress?

TTC#1 since March, I am 36 and he is 37. Neither of us have ever had a pregnancy before (never tried).
