10 days late !

So i have been trying to conceive for a while now and never had my period be late by 10 days. Ive been experiencing clearish white discharge. And its not ovulating bcz i ovulated 15-21st in November. We had unprotected sex on the day i had the highest change of pregnancy 33%. Every time i have the discharge come from my private part i think it is my period i wipe and just that clearish white discharge. I dont think its me ovulation late bcz i log on the glo app all the time and during that phrase my sex drive was high and so much discharge. I just want to know if its normal to have the clearish white discharge in early pregnancy around the time ur period comes.

Also i can feel when my period is coming bcz my uterus flutters and then i get it. I havent had any symptoms of period besides backpain

I have been cramping but the cramps are slight cramps on and off as when i get my period i have very painful craps the first day and it sticks and doesnt go away unless i take pain meds.

I will be testing tmr or Saturday and im eager to know the results.

So is clear/white discharge a sign of pregnancy?
