Hi ladies I'm just after some advice , I had a chemical January 24th , then on the 17th,18th&19th I had clear & creamy cm I started doing my clearblue advanced ovulation test on the 16th which was O on the 16th then flashing smiley until yesterday afternoon when I had my steady smiley face but I have no cm at all & haven't since 18th , is it normal not to notice any cm while ovulating ????
