Thanks nat..I will def ck out ff..havemt done that yet.
Ooh also if your having trouble diagnosing you positive opks then post ur pics online to us all and we will help you with that...they can be confusing little suckers sometimes..but you'll get the hang of it don't worry...I'd say if your going to use them start around cd 9 or 10...and use them everyday till you KNOW it's positive...a positive opk's second line has to be as dark as or darker than the control line...
Best of luck me petal...
