7w3d just curious if this is normal

Ciara
This is my second pregnancy and I didn't feel this way at all with my son, so is it normal to just wake up and not be nauseous or tired and no more tender breasts cuz just yesterday I felt horrible with all these symptoms and I have had a little cramping and my lower back been aching but no bleeding whatsoever.. Just curious if there's others that have experienced this in early pregnancy? Thanks in advance!
