14 weeks is this normal ?

This is my first pregnancy & I’m still not showing at all. However I feel the changes , the nausea , the faintness , & the uncomfortable feeling in my abdomen area. Almost feels like I can feel my baby on my cervix or uterus. It doesn’t hurt but it feels uncomfortable when I walk or stand up too long. Also a lot of my pants , leggings & belts feel uncomfortable around my pubic area. I thought it’s a little too early to be feeling this , could I be about to miscarry ? Very worried.
