Just added this but forgot information.. Needs some help!!

I just posted this but forgot to add some information. December 2nd till the 7th I had my period,I was late 6 days for my period and then got it on December 2nd! Before my period and now I'm having a lot of CM in my underwear,like I feel very wet down there all the time!! I just had a CM in my underwear that was gewy and white or clear!! Why do I have so much CM? My fertile days isn't till Wednesday and this has been going on before I thought I was pregnant but got a BFN then my period! I thought I conceived in September and then got my period later that month,and then I was late for my period.
