We tried to have intercourse, but there was a lot of pain, my period is now late

I'm 20 Me and boyfriend tried having sex for the first time(for both) and it was without a condom. As he inserted his penis in my vagina i couldn't take the pain and asked him to stop. Then we tried to do it in doggy style but i couldn't take the pain so asked him to stop so after that we just lay down and his penis was in my vagina but not beyond my hymen he did not put it any further. He didn't apply any force and did not even move to and fro. His penis was just there with no movement for less than a minute(maybe 20 30 seconds i don't remember). He did not ejaculate in me . I dont know if this even counts as proper sex or not. This happened on 9th February. And till then i have not got my period. I have taken no contraception as i dont know can i be pregnant or not. Please tell me if i am pregnant or not? I have issues with irregular period cycle. Please help me I'm really stressed
