Egg White cervical mucus as a sign of early pregnancy? - does cervical mucus increase if your period is due

Just wondering if someone experienced in the cervical mucus after ovulation egg white until she allegedly got her period and at the end is always a BFP?

I am TTC and chest pains and cramps, as well as an increase in cm. I have my period for 4 days.

Thank you!
