I'M WORRIED PLEASE HELP ME

I'm just having my period in this past two days, supposedly, my period is almost 7 days. I've had so much pain in my back that I couldn't longer bear to stand up, my boyfriend told me if we want to have intercourse, coz he knows if we do it, it will relieve the pain. When we do it, of course, it relieve the pain, seriously, but his condom got broke. He told me, he didn't release anything inside me. I'm just worried because my period supposedly will continue right now, but it suddenly stop. I'm worried if I'm pregnant :( can you please help me what to do? :(
