Late miscarriage scares me!

I keep seeing all these post of later losses. I know In every pregnancy there is a risk. If you had a later loss, I’m so very sorry. I have had early losses and it’s a traumatic experience, o wouldn’t wish upon anyone. My question is do you know why yuh had a later loss!

I’m just at 12 weeks now and I am so fearful. Thank you in advance for sharing your story.
