Could i be pregnant from precum ?

Okay so,

sunday, may 24, i had unprotected sex. (it was a stupid mistake)
My boyfriend didnt ejaculate inside of me, but i was worried about the precum.
about 20 minutes before he had *** already and i heard that sperm can be left in the urethra.

As a precaution, i took plan b on monday, the day after.

I dont have regular periods, so i dont know when my next period will be.
however, i do remember that in april my period was from the 11-17.

before that day i was very wet, kind of like eggwhite discharge for a couple of days. i have also heard that this means your fertile.

Just yesterday, i noticed that i've felt the urge to pee very frequently.
i have had a urinary tract infection before and it feels kind of like that, except there is more pee.

What are the chances of me being pregnant?
im extremely worried, being pregnant at 15 is the last thing i need.

you can very much get pregnant from precum.

you 15 and said you said its the last thing you need....why are you on birth control and using condoms?

you took plan b...that lessens your chance but know that its not 100% your going to have to wait n see

Ok there are so many misuderstandings about precum
precum doesn not contain sperm! the only time when precum can contain sperm is when you have ejeculated before. The pre *** will pick up the left over sperm from ur uretha and carry it out to the girl's vagina. However, ur urine kills off all the sperms that are left inside the guys uretha. Therefore, if the guy pees before sex and precummes, there won't be any sperms goin into your vagina and the change of getting pregnant will be very low.   Good luck
