I know this has probably been asked a lot, but could some of you please help me out. I have been using the Digital Clearblue OPK and have not yet had a positive. I think I am due to ovulate tomorrow and thought I would have a surge today but no luck yet. I have had EWCM, not huge amounts but some. Am starting getting worried that I might miss my opportunity and was wondering what is the best time of day to do the OPK and how many times a day should I do it? HELP!!! Really don't want to miss this months egg!!
