Probably a stupid question (tmi)

And I know perhaps it's been written elsewhere but what does the cervical mucus look like before getting a positive readings? The reason I say this is because my last period was December 7th to the 12th. I didn't calculate my bbt because I arrived to a new country and wasn't tracking when I had sex. But I know I had sex ALOT during I ovulated:) now the real issue is I don't want to test. And I have never had sore breast before since my breast reduction last year. My nipples are really sensitive and my cervical mucus is clear and stretchy. I started checking my bbt again and CM January 1st. Now the real issue is glow keeps pushing my period date. From the 4th to the 11th to the 14th and now the 25th. Period is a no show and I'm not stressing it at all. Just slightly curious about implantation and cervical mucus. I don't want to test because well I'm waiting till February. And I have to add that on Jan 18 I had cm that was watery with some brown only when I wiped after peeing, I put on a pad because I'm like Mother Nature showed finally.well guess again, On the 19th, around 5:30 pm I had wiped and it was a light pink like barely bleeding like a spot just a tad bit and my mucus was clear.then it stopped. Now today the 23rd my mucus is stretchy and clear. Am I ovulating again? Or could this be something else. I just want some insight. I have a doctors appointment feb 11th (navy doctor is on leave)
