Wow hopeful, I haven't heard from you in so long!! I am truly hoping your TTC journey will end this coming cycle! I wish you lots of luck.
Summermom, I use the CBE fertility monitor too. You need the official strips~ Cheese probably included the OPK's since they are handy to have and she doesn't need 'em! I don't know of any place that sells them inexpensively, if you do find a place let me know.
I buy mine from www.thefertilityshop.com
but their shipping is not that fast. You might have to buy some from a local drug store for this cycle. At first, you will need the 10 sticks, but after awhile you kind of know when to expect your egg symbol if it is similiar to the other months. I only use about 4 sticks per month, and I use the OPK's at the same time occasionally. I only use one or two OPK's, and then I can anticipate my O more accurately.
Oh, and hopeful, check out the donor egg buddy group on Fertility friend if you need info. Scroll down on the 40's board until you see the donor egg group. Lots of good info, and lots of pregnant 40's mommas with good info too!
