I had sex with my bf 2 days ago after 7 days of my periods finished

I had sex with my bf 2 days ago after 7 days of my periods finished. I had unprotected sex and am feeling some distubance in my stomach. It was my first sex ever. But didnt bleed out. N m worried about this that y I didnt bleed out. His penis went into my Virginia easily. I felt pain but I walked proper after this but felt so tiredness n sleepy. Plz tell me. Can I get pregnant n when I should test my pregnancy to be sure ?
