Cervical mucus help??

Okay ladies I recently posted about my breast being sore and having clear stretchy cervical mucus. My period was the 15-19 had intercourse on the 24th.. But Saturday the 31st I woke up to pee and went to wipe and had a bunch of mucus. Some people say could be fertility/ovulation but my calendar shows that I wasn't even fertile till 4days after I had the cervical mucus. It says my ovulation day was yesterday. I've had sore and tender breast for 2weeks now and I'm not due for a period for another 2weeks...could I may be pregnant?? Anyone experienced this?
