So confused please help

So I had my last period on May 26 over on the end of May I haven't got my period since, I had sex after June 17 almost every day till this date .. My period supposed to be here by June 23 I didn't worry about getting pregnant because based on dates of ovulation I wasn't ovulating so now I don't know if I am pregnant or not 14 days late on my period I took a pregnancy test today and was negative 😒🤔 how long should I wait to take another one?  Can I get pregnant 5 to 7 days before period? If the test is negative then where's my period? So confuse because I do the ovulation strips and all come out positive since the 20 of Jin till this date please give me ur opinion thank u !!!
