Help guys I'm confused!

Hey guys💜!!! So to begin with I had unprotected sex on the 25th and he finished inside me twice we had sex 7 days after my ovulation which ended on the 22nd. I took a plan b on the 26th and it's been 5 days since I took it, I do feel very tired, sleepy and dizzy at times and little cramps at times but my period is in two days I haven't bled yet from the pill and everybody on the Pill reviews says they had spottings before their period. Do you guys think I may be pregnant or the pill is working?
