Ask him. If you didn't see his semen, he likely ejaculated in your vagina. If it was less than 5 days ago, take a plan B. Otherwise, if you miss your period, you can try some pregnancy tests. I would recommend birth control in the future so then it wouldn't matter if he ejaculated inside you.
If you didn't protect and if you sex in 3 days you should be ise after sex pills
I never use after sex pills he didn’t use a condom
I know you have 72 hours for use after sex pills
Try to ask him if he remembered pulling out first. If he is unsure, I would wait 1-2 weeks and then get a pregnancy test as it'll be more accurate. Also look for signs of nausea or slight stomach pains.
However, if you don't want a child and want to lower the chance of having to get a clinical abortion, take a plan B as soon as possible. Even if you're unsure about being pregnant.
He thrust quickly and suddenly pull out but I been having cramps and weird discharge after I don’t if it’s my period or what
It might be your period, but if it is not, I recommend getting tested for a STD or UTI. If he thrust quickly, it could very much be a UTI.
What you need is plan B not a a pregnancy test. The test won't have any results for a few weeks or so. If your period is late by a week then it's time to take the test.

you could ask if he came in you? A pregnancy test becomes positive at day 10-14 post sex.
also get a swab or urine test bc that discharge can be STD
You didn’t know if he came inside you
Nah because he spit on his d then penetrate inside me and he just thrust quickly then stop I don’t know if he cum or what
I usually tell the girl I’m cuming lol
He just stop put on his clothes and smile at me my boyfriend weird anyways
If he didn’t pull out, then there’s a pretty good chance you could be pregnant. If you miss your period at the end of the month, wait until you’re a week later, then take a pregnancy test.
