It's hard to say whether it is a memory of an actual event or not.
Alot of people who have been abused in the past will be fine and have a wonderful life when out of no where a memory will pop up, something that they thought never occured when it could have. Memories pop up when the person is ready to start dealing and healing from the past, that's why alot of us get flashbacks.
Don't push to remember it, the more you push it the further you are actually pushing it back further inside yourself. Let it come on it's own, and if this is continuing then start asking questions, write it down, and if it's too much to take then it would be best to go into therapy to talk it out with someone who could help you with the abuse if that is what happened.
This is hard thing to think off, espeically if it's the first memory you have had, but there could be a reason to why it is coming out now. Take one step at a time, and don't force it out, it will come out when it's ready too.
Good luck to you, I hope that isn't the case for you, but it could be possible. The mind is a powerful thing, you just want to make sure that it isn't false memory, cause that can happen at times, but not always.
