i can relation to what you are saying.

my cycle used to be quite regular every 28-32 days pretty much.

in the last few months when i've been charting/temping, etc, it seems to be a lot longer. 35-40 days sometimes... far too long. i was ovulating at day 21 as well.

i know that stress is a big factor when it comes to my cycles, it really effects it. and the last few months haven't been easy.. quite the opposite really and this has effected my cycles.

i am seeing a naturopath to assist with a few health concerns i have... and i was speaking with her.. and she advised to get some blood tests done, so that we can sort out what's going on. as i may have some hormonal factors which influence my cycle to.

anyway i have been to my gp and got a form for the blood tests (not looking forward to them.. as i hate them !). and i will go and get them done.

from there we can work out the best plan of action.

so maybe go and chat with your GP and maybe they can work something out.

good luck
