Can a plan B make your next cycle late ? I had unprotected sex on the 20th & period was supposed to come the 24th so im 16 days late . I’ve been cramping and my boobs are really sore . Everytime I have unprotected sex it always comes late .

I once had a scare before my period didn’t come for while . It came down February 28th - March 4th & I had unprotected sex for my first time which was March 22nd . whenever I was due for my next cycle it didn’t come down until April 26th - 30th . Recently I had unprotected sex July 20th and i was expecting my period to come the 24th which it didn’t . Can I be pregnant or just ovulating late because of the plan b i took on June 22nd ?
