Am I pregnant??

Emalie

I had sex the 19th, 20th, 21st of august and within the ovulation week I was feeling nauseous and light headed my period is suppose to come in three days and I have been having lots of leukorrhea. I’m so anxious to know but I know I have to wait for my period to be late to find out. Is there any possibility to know what are some first signs within a week of pregnancy if so ? The leukorrhea is milky creamy white and it’s coming out a lot. Today I feel lightheaded when getting up
