I worry the same way. I go in on Thursday and I'll be 19+2 and that post now has me scared. And my babies movements are still pretty sporadic. But I'm sure both of our appointments will go as their supposed to.
Im 31 weeks and still feel the same way I think its just a thing all mothers worry about
I too get scared that something might go wrong. I feel my baby move everyday that helps keeps my mind a little at ease. I go in for an ultrasound tomorrow & I'm just trying to think positive.
