Late period

princess

I had sex on the 15th which is the week before my period, then I had sex on the 18th which is two days before my period. My period was supposed to come on the 20th but didn’t then I had sex on that day and I had sex on the 22nd which would’ve been the third day of my period. I also caught the flu some days ago, am I pregnant or is my period pushed back? Please help
