Might sound crazy, stillbirth?

Lately I have been having this weird funny feeling fearing that I will have a still birth. I was on TikTok and out of no where this video of this young lady had a still birth and everything was so healthy up to that point. & what I noticed was that a lot of women who had still birth the gender was a female and idk if I’m just freaked out or comparing how I currently feel to what I have seen with me but I am a nervous wreck. This will be my first daughter and last child( =3 kids) & I am 18 weeks and she barely moves I still sleep on my stomach or back and geesh I pray for a happy save delivery and recovery for my baby and I.
