should I be worried...

Hey guys! So I recently had to take a plan b. Because well...you know . But I ended up having unprotected sex on a high risk day without realizing (please don't judge, very stupid I'm aware.) but if the pill brought my period two days later...should I be worried? The period that the plan b brought is now pretty much gone but I'm cramping a bit...but I also do have my regular period coming on the 12th so it's not uncommon for my On my way! To start kicking in around this time. I was going to take another pill but I don't like the effects of the pill and I just feel like it's not good to take them period. Can someone please help me to the best of their ability? Currently panicking a bit here 😩
