Pregnancy scare?? Help??

So I grinded on my boyfriends dick like 5 weeks ago. And 9 days after that I got my normal period so you would think everything’s good. Idk why I’m so worried but I was wondering if there was a chance I could be pregnant. To me it doesn’t sound logical for me to have my period and then think I’m pregnant. He didn’t cum but Precum is still dangerous, however I got my period 9 days later and it lasted 7 days. What do you guys think? Please let me know what your opinions are. Do you think I could be pregnant?
