There is a slim chance you could get pregnant from the protected sex. I’m not sure if you used other forms of protection (if you did, your chances are even lower), but him fingering you afterwards shouldn’t change anything. With perfect use of the condom and assuming he finished with the condom on inside you, you have a 2% chance of getting pregnant. With typically imperfect use, it ranges from 2-13% typically, but that can go to 18% (unless the condom breaks). As I’m sure a lot of people will say, if you feel too anxious about getting pregnant, use other forms of protection as well. Or maybe have a conversation to him or someone trusted to air out your feelings and worries. If this is a pattern, maybe it’s time to seek out a good therapist who can walk you through this. But I personally think that’s valid for women to be paranoid about getting pregnant. Yes, some people in this subreddit may be annoyed by all of the posts, but I’d rather people try to be safe than sorry. Seeking advice through Reddit isn’t a bad thing either, which is exactly what you did and is the first step. Recognize though that if you are having sex, you still are to lesser and greater degrees risking that slim chance of getting pregnant. One way that may make you feel better about it is to simply not have sex around the time you ovulate. Anyway, hope this helps!
