5-6 weeks and cramping!

Hey ladies, so my period was due November 4-5th and I have been feeling “crampy” in my uterus since then! At first I thought my period was going to come because I felt that way for couple days, but it never came! And I found out I’m pregnant! 😊 BUT is it normal to feel really uncomfortable and crampy? I’ve felt crampy on and off basically everyday for a week and a half!!! Same with my lower back! Just really uncomfortable in the uterus/ sometimes ovary area. I’ve read it’s normal, but I just want to make sure others have felt this way! If you could please comment that would be great 😊😘
