Growth spurts

Sabiha
Hello everyone. Hope everyone is good? Just posting because I'm a tad bit confused. Had a scan done last Friday and everything is going well with my little peanut. Was measuring at about 22 weeks couple of days and we found out I'm a whole week ahead. I'm now 24 weeks. Are growth spurts normal? I'm sorry for the silly question. It's my first pregnancy hence the question.
