So I was sick (bronchitis/sinusitis) from Sept. 23 to around Oct. 6th. On the 7th I started a second period. The blood has been much less in quantity and seems to be thinner and lighter in color. I have been under extreme amounts of stress these few weeks and in the weeks to come, so I assume that’s the problem. But any other thoughts/opinions/ advice is welcome.

I am not having sex and am not on birth control.

Edit: this is the 2nd time this year (and ever) that my period has been irregular)
