help!!

I have had sex 4 times this month between periods. It was all protected. But a week into my BC I forgot to take a pill and didn't take it till the next morning with my next BC pill. So I took 2. I knew I wouldnt be protected so I used condoms every time we did it. None broke I checked cause I like to make sure. So I am now on the 1st day of placebo pills and I had sex unprotected, but doing the pull out method. I was worried because I did miss a pill this month like I said before and I always hear about precum how you can get pregnant from it. So I took the plan b pill just in case and now i think I unnessicarily took it. Opinions? Should I worry? Is my period going to be delayed?
