3 days late

Mallory

I'm 3 days late for my period to start and I took a test and it was negative. Could I still possibly be pregnant? Did I test to early. My husband and I had unprotected sex 8 days in a row at the end of august and I have been hoping and praying for our first baby. I also have been having sore breasts, cramping and my skin has been more oily and acne.
