What y’all think?

So me and my boyfriend had unprotective sex only 3 times this month but the sessions are usually short , he didn’t cum or anything and he always cleaned himself before we did anything , I haven’t had any symptoms of pregnancy but I am 5 days late on Jan I had my period the 23rd then on feb I had it on the 25 and now it’s the 28th :/ idk if it’s just my period being weird and coming late or am I pregnant ... i took a test but the test was probably bad
