Why could the condom be so wet

My boyfriend and i have tried to be really careful and have used a condom every time we've had sex. But, when he pulled out after wards, the end of the condom felt weirdly wet. So we checked the condom by squeezing it and no sperm came out. So we're pretty sure the condom didn't tear. Why could the condom e so wet afterwards when it has no tears? could i be pregnant?
