Help!!

My boyfriend and I had unprotected sex on Tuesday January 15th, which according to eve was my ovulation day, and he didnt pull out. Then on Saturday I started experiencing cramps like my period was coming but it never came and it was not steady cramping it was off and on and that’s still happening as of today, it was very abnormal for me because thats never happened before. Normally when I start cramping it’s because my period has come. I’m trying to be patient with taking a pregnancy test because my period is still 5 days away but I’m so anxious
