Did I O?? Advice please

[armywife03]

I am CD15. I normally O on 12 or 13.I noticed EWCm 3 days ago.So much that it literally was dripping out after a BM(Sorry) I normally have pressure then cramps on either the right or left.This time I have only had mild cramps kind of in the center. I dried up a little to what I would say is watery over the past couple of days. Normally right after I O have get thick creamy and then to sticky almost right after. Well let night I took an old OPK just to see and it was almost positive just a little lighter than the control line. I am wondering if all the stress of my husband leaving has caused a delayed ovulation or something. I also started having fertile cm 6 days ago.I heard that the day of your most EWCM is O day??? I would appreciate any advice thanks
