Pregnancy test

Sooo 🤣Last time i had my period was the 24 of may thats wen it ended, & the next day my boyfriend came to visit so we had sex a lot probably the whole week 🤣💀 & there’s 3 days left in this month. so I’m kind of worried because i haven’t got my period and i was feeling kinda dizzy at work like how i felt when i got pregnant with my son. i took a test and it came out negative so i thought i was good i waited a few days and noticed my period still didnt come and maybe the test was bad so i took another but the test is still negative so what should i do ? Should i just go to the doctor or wait alittle longer to try another test before i go
