15 weeks pregnant and feeling nothing

Hi Mummies, I am currently 15 weeks and 4 days pregnant and I don’t feel much. I do see little bit belly but I feel like it is a fat belly and not pregnancy belly. I don’t feel any baby movement as well yet. Just feel sharp pain on and off in right side of abdomen! Feeling almost nothing is making me worried. Did any of you experience this? Is this normal ? I keep thinking that since I don’t feel much, may be baby development is not happening properly :( This is my first pregnancy and hence I could really use some advise. #PleaseAdvice #preg1stbaby
