opk question

My question is since my m/c 01/09/07 my cycles have been ranging from 29,32,27,and 32 days. I am currently on cd8 and have decided to use opk so when should I start testing I have 7 strips in the kit. It seems to go short cycle then long cycle so if it continues to do it that way I am due for a short cycle again,before m/c my cycles were 28 days.

I would just start testing right away.  If you use up the strips too soon, and can afford it, then start now and buy more if you run out.  I tested from the very first day until I saw the double lines...and it worked well!

I'm similar to that since my mc. I used to be 28 days and range from 30-35 now. I have o'd from cd14-cd22. I always worry I may get back to normal and o early and miss it if I don't start testing on cd8 or 9.
