Help please!!

Kyra
I am currently 6 days late on my period. I was supposed to start on the 21st. I took a test a few days ago but it was negative however I didn't use FMU. I have a light cramping the past few days but they don't hurt like my period cramps usually do. I had sex three times unprotected during my fertile window and more times after that. I've started to feel sick when eating food I usually love. I couldn't even finish my food because it made me feel so nauseous. My nipples are extremely sore to the touch. For a about a week I had large amounts of white creamy discharge with no itching or smell. I'm just confused at this point. I've had to move my period back twice because I still haven't started.
