Pregnancy

Well me and my boyfriend had sex during my ovulation. Two weeks ago And for the first few minutes we didn’t use and condom. Later that night he said pre-cum can get you pregnant but it is a low percent. And a day after my nipples were sore and still are to this day. And I am two days late on my period and I don’t know what to do can someone help me. And maybe give me some tips, advice, or information?
