Afternoon? Just wonder if anyone can offer some advice? I got a positive opk on Wednesday and that carried through to Friday. My last day of EWCM seemed to be Thursday. I started to get pretty painful breasts on Saturday. My mucus is more of a creamy texture now and today I noted that my cervix was rather firm and closed. We last had sex Every day last week from the Sunday to the Thursday. When do you think I ovulated?
