I'm 22 weeks tomorrow and I'm so overwhelmed with the fact I haven't felt him move yet... I know it could take a few more weeks I just hate the fact that I have literally no signs that he's okay I get a lot of back pain and my belly is definitely growing fast but I'm just scared he's not okay that something is wrong I go to the doctor in two days to make sure he's okay and I'm praying he is. I'm sure its just a mommy thing to worry like this but should I be concerned idk?
