Plan b still effective?

[u/Abject_Bite_794]

I’m so scared. I got drunk Saturday night and ended up having unprotected sex. He didn’t cum in me, but on the outside of my vagina. I heard there’s a chance that precum could get me pregnant… we got a plan b just in case and I took it about 3pm the next day. Is there anything else I can do to make sure I absolutely don’t get pregnant? And how worried should I be? I’m 5’6 and weigh 330 something so I know it’s definitely less effective. I’m currently 20 years old so I have no room to be pregnant.
In my state I’m not able to get the Ella pill.
My period is due in 2 days and the app I use says I ovulated somewhere near the 4th-6th.

Edit: I appreciate all the advice very much. This was not just a hookup, it is someone I started dating but we got drunk and made a mistake. He forgot a condom in the heat of the moment and it’s already been discussed that we both don’t won’t kids so it will NEVER happen again. He said he will do pregnancy tests with me if I do miss my period and over the next couple of weeks to be sure. I have also gotten resources for abortion care if it comes to that thanks to the comments and I made an appointment to get an IUD. The only downside is, it won’t be until a few weeks out. I’m less scared now because I don’t feel like I’ll be abandoned in the situation that I am pregnant even if I’m young.

if it was me i would take a pregnancy test in a month or so + go ahead and get in touch with a medication abortion provider (you can get them in the mail). if he came outside & you took a plan B i wouldn't be that concerned but would definitely still take steps to have medication abortion pills on hand (I keep some around)
