plan b now period but no bleeding

hi ladies. I took a morning after pill a few weeks ago, I had spotting after one week of taking it. and now my period is late 2 days so scared I might be pregnant. I feel cramping like my period. and I had slight brown mucus in the morning. I could've sworn I was going to get my period. I just feel it coming. but it's not here. used pull out method and later condoms throughout the month. any opinions?
