We used a condom but my girlfriend found *** when she got home?

So me and my gf just got done with . but when she got home she told me she found ***? i didnt inspect the condom this time around and i dont think it broke. could she get pregnant? i asked her if maybe she was just wet. but she said the female body doesn't produce what shes having...im hoping its just lubricate mixed with her own fluids??
