Could I be pregnant? Hmmm

I had sex last Wednesday when I had a 33% it was unprotected & he pulled out about a second before he ejaculated & then we had sex again a few days later (9% chance) & he ejaculated near me and some of it spilled over my vagina. I checked it the restroom and I'm not sure if mucus came out or sperm it was white and cloudy. Now I'm about 6 dpo and I'm having dull cramps around my abdomen & lower back sometimes it feels like a pulling pain on one side to another.
