3rd trimester

So I've had 3 loses in the past with 2 healthy births. I will be 27w Thursday I was so excited until I seen a post that someone lost there baby at 25w 😭😭 now I cant eat cant sleep I had a panic attack ... I feel so bad for this lady... my last appointment was at 24w ervything was great I go back at 28w 4d ... I'm just so scared this would happen to me. I feel her kick and move 💜 why do these things happen? How do they happen? Is it something that happened earlier on and cought it at the appointment? If I feel my baby kicking then I shouldint worry right? I'm a complete mess sorry for venting 😭😭😭😭😭😭😭😭😭😭😭
