Hello! I Am 32 Years Old Have A Clockwork (literally

Hello! I am 32 years old have a clockwork (literally like 6/7am everytime) cycle of 28 days. Lmp was 10/15. On day 13 and 14 of my cycle I had very light red bleeding that just suddenly stooped (this has never happened to me before). I am not on birth control. My husband and I have used pull out method for last 8 years because getting pregnant, if it were to happen, would not be a problem for us. Another weird thing that is happening is that instead of getting my period yestersay ive had increasingly A LOT of clear, sort of wet white chucky, discharge tot he point rhat i think i need to urinate but i dont and im typically very dry. I feel the contant need to pee also. I,took two pregnancy test 1 yesterday morning and this morning both with first morning urine and bith were negative. Could i still be pregnant or could there be something else going on? Please help! Thanks
