trying not to panic....😞

Maddison
So my next appt I'm suppose to find out the sex of our baby and I'm suppose to get test to see if the baby is ok, such as like for Down syndrome and stuff like that. Well on my other birthing apps it made me scared as hell...literally. That I'm going to get a needle put into my stomach/side ect? That I could have a miscarriage? 
What do I expect from this? 😭 all I can do now is think of everything that could go wrong.Â
