Could i be pregnant ?

I’m on birth control & my ex partner tends to not pull out when he’s abt to cum & I’m always fine bc I’m taking my pills correctly. Even when i wasn’t taking my pills correctly & he was cumin inside me my period came at the end of the month. However we’re no longer together but we had sex one last time on the 13th & he came inside me twice i believe & i was suppose to get my period the following Thursday the 20th (when i start spotting) & start bleeding on the 22nd. It’s the 25th & i still have not bled. On the 23rd i noticed eggwhite discharge. I’ve been super tired (but i also just started a new job) & I’ve been having headaches & im lowkey constipated. Should i take a pregnancy test or is it too early to tell ?
