Thanks @AJsyd and @Lizard
AJ I hope your cycles even out soon for you, sounds just like mine when I came off the pill too. Mine are still about 35 days now, but hoping to get them down by a few more days if possible. The only time I had a 31 day cycle (the shortest one yet) was when I took vitex. I've decided I'm going to wait until AF is over before I start taking them, then take them all cycle except for AF from then on. I'll let you know if they seem to make any difference!
Lizard, I'm sad for you that the financial part is throwing a spanner in the works for you at the moment. I hope your DH manages to find another job soon so life will be easier for both of you! It's so stressful looking for work and worrying about money.
