Worried about having an incompetent cervix!! I have no risk factors! Advice? Help? Success stories with an IC??

Alexis • Expecting our sweet baby boy in April.💙 I thank God for giving me such a wonderful opportunity!
I'm 18 weeks pregnant today... and here lately I've been reading online (I know, bad thing to do) and I've learned a NEW and UNWANTED thing that can happen in pregnancy... I've heard of people losing a healthy pregnancy due to incompetent cervix.. the baby literally just slips out without any pain or anything... and now I'm worried that it'll happen to me... I don't want to lose this baby😭 Can someone, ANYONE please tell me how common this is? I have no risk factors of the condition but I'm just very paranoid being that I'm a FTM...😩 Someone please help..!
