How many days does EWCM last before Ovulation?

aloha7

Hi there, I am on day 2 of EWCM (it is alot of eggwhite-like cervical mucus and there is quite alot), but I did not get a positive OPK today yet. How long does EWCM last before usually ovulating/getting a positive opk? I wanted to try tonight but my husband is not in the mood so i am quite annoyed that we might hve missed a chance because i know eggwhite CM means the sperm can live up there untill ovulation.

Also i very much feel my ovaries (ovulation pain) so i know ovulation is righr around the corner.

What do you guys think? How long can the ewcm last before getting a positive opk?
