Your miscarriage experience

I’ve never had a miscarriage and am currently pregnant with my first.. I get scared all the time if I even get a bit of pain since I have no experience with miscarriages or know how it feels. I’ve always been curious to hear from you guys if you wouldn’t mind how was your experience? Was there pain and how far along were you? And how did you find out you lost your little one if you were further along pregnancy? I know going through that must be hard and heartbreaking.. My heart is with any of you who have gone through it.
