Ovulation does not necessarily occur two weeks after your period starts. A better way to measure by counting days would be to count 11-16 days backwards from your period starting. If you have a regular 28-day cycle and a "normal" 12- to 14-day luteal phase (the time between ovulation and your period starting), then these numbers coincide and ovulation does occur about two weeks after your period starts. But if you have a shorter or longer cycle, then counting forward from the first day of your period could really screw you up as far as timing goes.
To answer the CM question, thick and cloudy sounds like you could be approaching your fertile time. Is it really stretchy? That's the best way to know if it's nearing ovulation time for you. If you get some in your fingers, you should be able to pull your finger and thumb apart and it will stretch the whole way. If it doesn't do that, then it's not your most fertile time yet.
