Bad cramps at 4 weeks?

Co

Hi! I’m 12 DPO and found out yesterday that I’m pregnant. My first symptom was really bad cramping on 9/10 DPO. The cramping is getting more frequent and worse. I’ve had several kidney stones and the pain is reminding me of that. I feel sharp pain on my left side. Sometimes it’s just mild cramping. I’m so worried it’s an ectopic pregnancy. Could someone help put my mind at ease? I’m hoping it’s just a kidney stone. My doctor’s office said bad cramping can be normal in early pregnancies. This is my first so I’m very clueless. Has anyone else had this and had a healthy pregnancy?
