could i be?

-i had sex on the 1st and 3rd of january (withdrawal used)

-i had my normal 5 day period the 5th-9th

-today i had this discharge when i wiped (i always wipe ‘deep’ to check for my fertile window more accurately) (i was sort of aroused)

-i’ve been kind of nauseous on and off and honestly don’t know what’s going on

-i also have come and go headaches

any advice?
