Am I pregnant?

It's extremely possible. Seeing that pre-injection carries more sperm then the actual ejection does and it usually lays closer to the uterus . Yes, very much possible. I'm not sure how old you are , but you should not be having sex without protection on both ends condom is a must in the pill or some other type of pregnancy prevention is necessary . Remember sex primary function is to procreate children. If you are not ready emotionally, physically, spiritually and financially to do that, then you should wait until the right individual that you know will stick around and help you and is your partner, your best friend, and is compatible to you to have children, then you wouldn't be in this situation, if you dodge the bullet, this time take this as a lesson and remember what I typed here you have to deal with the individual for 18 years of your life for five minutes of pleasure take a risk every single time you have sex of becoming pregnant. Even with protection, no protections, 100% think about it the next time this issue comes up

It only takes one and a drop contains lots. Best to not be stupid next time.

It's actually possible but it's very slim.

Thanks guys, but I got my period. I think I'm alright. Thanks for your answers though!
