At six weeks pregnant, slight cramping can be normal. It's a sign your uterus and the surrounding tissues are expanding to make room for your baby. If you feel pain more severe than usual period cramping, especially if accompanied by a fever or diarrhea, contact your doctor immediately.
Yes it's normal because uterus is starting to expand. Headaches are also normal, also be careful of dizzy spells.
Thank you for your advice 😊
