am I pregnant ?🤔

Hey guys, so I'm a little confused as to what's going on. I took plan b last month on may 6th a day after being intimate, and got my period in four days. My husband and I continued having sex and I feel like at times the condom was unreliable. Anyways, my period was 8 days late this time, and I THOUGHT I got my period yesterday but it was just a little bit of blood and cervical mucus, and then it stopped within a few hours......what's going on? I know that taking plan b messed up the menstrual cycle but 🤔🤔🤔🤔
