How will I explain my self harm scars to my daughter?

I'm currently almost 18 weeks pregnant and I just realized: I'm going to have to explain my scars some how. And they're bad. Like, bad bad. I cant explain it away with an accident or a cat excuse. I don't want her to think it's okay since mummy did it. What will I do? 😥

Thank you for all the wonderful replies! Lots of my scars and on my arms and legs and very noticeable and most needed stitches as well. I will make sure my daughter always knows I'm there for her at any time, and pray she never feels the need to hurt her self!
