Hey babe! I'm so sorry to hear your fustrated and are having issues with ttc! Firstly the discharge thing... Sorry to Be the one to suggest it but maybe (big maybe) it was a m/c. I had one about 3 years ago and it was excruciating, I had really bad cramping and a large amount of tissue and heavy bleeding. After I had my m/c my periods were very irregular and 'different'. But in saying that I may be totally off course about your situation. Regarding charting your ovulation period I would highly suggest instead of counting CD's (which can be a reliable method of charting) try to take your temp every morning before you get up, chart your CM and testing with ovulation test strips. I have used the maybe baby and for me personally with DS it didn't work at all but have had reports of it working so that's totally up to you but I find charting CM and test strips the best. I have a 28 day cycle and I usually ovulate on the 18th day so not right in the middle of my cycle so I don't beleive that every woman ovulates right in the middle of thier cycle. I truely hope that you have some luck soon! If you do have to go to the doctor about this they will most likely ask for some charting details and history etc so might be good to start now. Sorry for rambling! Xx
