Possibly pregos

So I had unprotected sex. He didn’t come in me at all. But I’m on bc. I haven’t started my period. Ever since I got on bc months ago it’s been wacky. Idk if this is just my body having another wacky period. I had splotting. Should I not take my bc until I get my period? Or should I test. Or am I pregos. Help please 😬🥺
