Can I get pregnant from Precum?

Hey girls!

So my boyfriend and I tried to have sex for the first time on May 4 but he only put the tip inside and I told him to stop because It hurt too much (it was my first time trying it).

We did not use protection and although he did not ejaculate inside me, I am worried that some precum could’ve gotten inside my vagina. Also, my period came 2 days after we tried to have sex.

Do you think there is a possibility of me being pregnant? I am very confused 😣

Help please!
