Im scared i might be pregnant

I had an situation where semen maybe could have made its way into me. It happened on the 31st of may and i was spotting that same day because the next day, 1st of june, i started my period. My period ran its course and I supposedly started ovulated on the 17th of june. I did notice some brown discharge from the 15th through the 17th of june. I dont know why but it happend last ovulation so I don’t know if that’s normal. Now its july 1st and I didn’t get my period. I’m still hoping it’ll show up tomorrow or maybe on the third but i am scared i might be pregnant. I dont know what i would do if i was and i know this isnt much information and you aren’t doctors but what do you guys think? I just don’t know what to do. Anyone with knowledge or experience might know whats going on?
