Bloating and cramping ?

Erin • Second baby boy due July 9th, married !
Question this is my second pregnancy my son is 5 years old and I just found out I'm pregnant !! I'm a little over 4 weeks ... I have been so bloated and having mild cramps ? The bloating is a little uncomfortable. Is this normal ??? I can't remember if I went through this discomfort with my son seeing as it was 5 years ago. Thanks in advance for any help
