A new cycle...early again

My bleed began today... Early. 33 day cycle, ovulated cd 22 and bled 11 days later. This cycle I am using a moon cup. I am feeling allot of cramps in my belly and lower back, and that uncomfortable full/swollen feeling in my vulva. Didn't get that last month. Not wanting to use my cloth pads though this month as we are away traveling on Saturday and the weather is a little too wet to guarantee washing will dry by then.
At least bleeding now means I wont be when we fly!
