Unprotected sex

Me and my significant other have unprotected sex and pull out, we aren’t actively trying for a baby but if it happens it happens, we already have a 1 year old. But lately the last two nights after sex when I sit down on the bed I noticed I leave a wet spot on the bed after getting up and I usually remember leaving wet spots when he ejaculated in me in the past. My question is did he pull out late/precum or could it be female ejaculation making its way out?
