Oh, I totally understand how nerve-wracking this waiting phase is, I used to overthink every little detail and get so anxious! Yes, there is a tiny risk if the fluid was close to the area, so try to take a deep breath and test once your period date passes.
Let me be very direct: if semen or pre-ejaculatory wetness got near the vaginal opening, there is always a small chance of pregnancy. Don't take chances, use protection next time to avoid this stress.
With my PCOS history, I know how unpredictable fertility can be. Honestly, if there was any direct genital contact, even pre-cum or wetness can sometimes carry sperm and lead to pregnancy. It is always better to be cautious.
Instead of stressing and searching online, just buy a 50 rupees home test kit from the local chemist once your period is missed. It's the cheapest and most practical way to know for sure before you plan any doctor visits.
Listen dear, don't panic too much. While the chances of pregnancy from just wetness without full penetration are quite low, sperm can occasionally swim up if there was direct contact. Wait for your period, and if it's late, take a simple test.
I usually stick to my safe prenatal walks and light yoga to keep my mind calm, but medically speaking, any wetness that contains active sperm can pose a small risk. If you are anxious, checking with your doctor is the best way to get clarity.
