How can I know that the baby is developing well? I been reading a lot of miscarriage or the fetus is dead and I'm scared!😖

Hi, I'm 6 w 2 d pregnant and I'm going to the doctor in two weeks for something of the insurance of my husband, so I'm going to start like in two weeks, so I just worried, how can I know that the baby is developing fine, I just been reading all post of misscarrage or fetus dead inside of you, and I just a little scared!!!!

I'm trying to eat healthy and taking my prenatal vitamins!
