Hello mam, thanks for trusting health care magic.
In my opinion you should take ample rest as most probably it is exertion related and in case still it is bothersome get a pelvic ultrasonography
If everything is normal then wait for periods but if it is abnormal visit a gynecologist immediately as this can be a tubal pregnancy
In case you have further questions you can consult me on health care magic forum and i will be happy to help
Take care and wish you all the best.
Dr Manisha Jain.
