Feeling baby move early

Cash

So this is my 3 rd child and I was told by someone when I had said I can feel bby move already they said that’s nt true ok so then I got a ultra sound few weeks ago nurse stated baby is movein and kicking I’m 7 weeks give it take bc I have nt had a measurement yet that happens in 4 weeks do I here the baby movein n kicking . Ok so then what I felt was the baby movein then why did the lady that wasn’t a nurse say it couldn’t be movein Like every body is different I feel my baby kicking n movein . At 7 weeks ! Crazy but true n then I’m super nervous bc few people said I’m havein more then one bby due to early positive befor 4 weeks n period was due n dark positive but ya jus super nervous .
