Pregnant?

lexii

hi all, please be kind as I have had severe anxiety regarding this situation. I was a 23 year old virgin, with a regular period so being on birth control was not needed for me. That being said on May 27. I drunkenly had unprotected sex for the first time, he barely put it in because it didnt break my hymen, and he did not finish in me.. but obviously im reading things and concerned about precum. To be safe I took a plan B less than 48 hours later I had some spotting a week after taking this, but am not due for a period until June 19. Should I be as worried as I am? TYIA (yes i read the side effects of plan b but im still stressed that im pregnant lol)
