Possibly a stupid question so bare with me... I have just noticed some ewcm and feeling very excited as I haven’t really had it before. Flo estimates that I’ll ovulate on Tuesday which is cd18 for me and when I’ve ovulated the last two cycles confirmed by opks, clear blue ovulation pains and temping. I’m temping but not doing opks as dh does not want me to this cycle to take away some stress. My question is really, is it likely that ovulate on Tuesday or before? I’m not sure how long ewcm is meant to last before o. How long do you usually have ewcm for before o? Thank you and hope that made sense
