8 days late

I’m 8 days late on my period. I’ve been tracking my ovulation because I’m not on birth control so me and my boyfriend rely on condoms instead. Well we had sex without a condom on my peak day of ovulation😅 I took a pregnancy test yesterday around 4pm and I’m pretty sure I didn’t see a line but still no period. My period is rarely a day or two late and now I’m stressing. Any advice??
