Am I Pregnant

I had unprotected sex like multiple times on my most high risk obvulating days, and I am not on any birthcontrol, he did cum inside me the first time, pulled out half way. (Lol) but during that day we did it like 3-4 times, the next day 6-7, and then the next day like 3 times. This was about 15-16 days ago, and I am now going on 3 days late from my period. My periods are usually regular. And I have had this period cramping feeling on an off for the last 2 days. I have been eating alot , I feel kinda in the dumps. My boobs are extremely tender at the nipple, and I have this creamy white discharge not very thick , more thin. What does pregnancy cramps feel like vs period cramps? I just feel bloated and have to pee alot as well. Ladies what do you think
