When to take a pregnancy test

mariah

So me and my boyfriend had unprotected sex 07/22 I supposedly ovulated that day 🤷🏼‍♀️ (I don’t actually know the date I ovulated didn’t track it) but I forgot to take a plan b that night so I did it the next day plan b’s usually work for me so I thought nothing of it until my boobs started hurting for the past 2 days not the normal boob soreness you get when you’re about to come onto your period it’s more intense it feels like little stabbing pains on the sides of them I was supposed to start my period yesterday it may come today I heard it can be up to a week before your period starts so if it doesn’t come today I’m just wondering when do I take a pregnancy test? 🤔
