feifei, sorry that you are finding it so frustrating on the OPK but do you know agar agar when you ovulate, maybe better to test it around the period. For irregular cycles, it will take a while to know when the period is ow, u jus end up test negative for days and days. When I first started, I am also like u, test until I give up liao cos keep showing one line only. For me, when I have two lines, I just BD liao so that dun miss out any chance.
Cheryl, dun worry too much. I am also waiting for my test result which will be out tomorrow. Keeping my fingers cross for the past weekend. Very worried cos I am above 30 years old already. But friends keep telling me that blood result will usually improve the probabality substantially so lets be optimistic.
