Fingering with precum

[nwfb1001]

On 26 Jun, I had some intimacy with my girlfriend, and I had fingered my her (inserted my finger into her vagina).
I did not ejaculate at all for this time, but I am now very worry that there may be precum on my finger (since I did some handjob for myself) which I used to insert my gf's vagina. My gf's period came on 21 Jun this time.
I am now very worry that my gf will get pregnant due to this event. May I know that if there is high probability that she will get pregnant? Thanks for answers

Dear nwfb1001,

We know that pre-cum can contain semen. From your description, it seems like the risk is small (looking at your girlfriends last menstrual period and the question of whether or not there was pre-cum) If you are worried about pregnancy, visit your local doctor to ask for emergency contraception. You are still within the time frame (max 3-5 days after sex depending on what medication)

Thank you
