Pregnancy or no

Hello girlies,

I have a question for you.

I had sex couple of weeks ago beginning of Feb where i was ovulating couple days before i had an un protected sex with my partner.

I was supposed to get my period Feb 21 but i have been having spotting for the past 4 days, i did i test yesterday but it said i was not pregnant . I usually never spot even if i do the next day i get my period but right now i have been having spotting

Should i re test again or wait
