Fear and worry

So like I’m sure I’m not the only one that feels this way but how does everyone cope with the worry of miscarrying or still birth? I think reading some post have kinda scared me and now if I feel any little cramp I start to worry. I’ve never really had a miscarry before by the grace of god. I’m sorry if I upset anyone with that comment but I have two living children 14 and 11 and like idk I can’t help but to worry. I’m 12 weeks will be 13 this coming week.
