I have never posted, just read a lot. I have been TTC for over a year with no luck. My cycle is like clockwork and my CM changed as it should. 2 red flags... I spot before my period about 3-4 days and after 3-4 day EVERY MONTH (I thought this was normal until recently). And OPK never show a positive. They get darker, but has never been as dark or darker than the test line. I go to the doctor in 2 weeks, I want to have all the right questions in line.
