Pregnancy or Period?

b❤️

If I were pregnant it would be week 4, I’m a day late of my period. I have had some slight nausea but nothing that’s lasted over 5 mins and that’s for the past 3 days now. I’ve had a milky white discharge and what seems to be a light pink and light brown discharge too, I know I’m sexual healthy. I did have unprotected sex Tuesday, August 21st. Opinions?
