Could Stress Cause Your Period To Reduce In Length And Amount?

Yes, and for some woman they loose their period for months because of stress

Yes  stress  can cause  irregular  menstrual cycles

I've been on my period for almost a month, but it is very light and on some days theres nothing at all. I'm assuming it is because of stress over the past 4 months, causing a hormonal imbalance. But should I be worried? = /

I have always had high levels of stress in my life. My cycle has never been shorter than 5 days. I have been charting my cycle for the past 2 years. My last regular-irregular cycle was April 1-5. The one that followed (the one I am concerned about) started off light attached with a weird pain (not my normal craps that go away with medicine). It started on the 26th and lasted till midday next day. I used tampons for those days and the majority of it was brown. On the 28th no period, no bleeding, no nothing. I waited till yesterday May 18th to take a pregnancy strip test that I got from early-pregnancy-tests.com. Both tests came out negative. But if this last experience was a period my next period should come the weekend of May 21-23. So that is what I am waiting for. But normally by this time, I would be experiencing belly pain, bloating and irritability. I am not having any of this. Does anyone have any advice or insight to my situation?

I have just noticed that the last three periods have been pretty light and I wondered if it was due to stress. I'm pretty sure I'm not pregnant! ; ) I am 37... Something I have noticed is that my periods get heavier if I lose weight!! Which is not very often but thought I d just throw that in!
