Should you use the opk's twice a day?

Question

I've been testing at 1pm everyday should I be doing it again later on?

Answer 1

I read that some womens LH surge comes and goes quickly and its recomended to take it twice daily to make sure you catch the surge.  

Answer 2

I have ready that the later in the day the better.  I was always getting -, so I started doing twice a day and this month I finally got a positive. It was also the same day I got EWCM and my temps dipped before the rise.  So it was accurate as well.

Answer 3

Your surge can happen very suddenly and if your previous test at 1pm is close to positive, you might want to take another later on. I surged late in the same evening after taking an OPK at 2pm. By all, take a second on if you think it is a good idea. I wouldn't want you to miss that surge! Best wishes to you!
