almost 18 weeks... want to feel the baby

So I know it is different for everyone, but I really wish I could feel the baby moving ☹️ I think I have felt him now and again - almost like a little bump or bubble popping - but every time I try to really focus on it, all I can feel is what I think is my pulse in my lower stomach 😞 I know it's still early to some, although I know I also see a lot of people on here who feel their baby earlier than this 😕
