Sharp pain right side 1.5" from right hip, 5" slightly diagonal from pubic bone, radiates front to back. Started menstrual cycle a little over 48 hour?

Unsure. Could be several things. If it is severe or persists more than several hours then you should be evaluated. Sorry but the list of possible causes is long. With any type of abdominal/pelvic pain, best to be seen. If any fevers, vomiting, diarrhea, sudden worsening of pain, please be seen right away. Sorry this was not more helpful. Best of luck with this. Dr R.
