Hello mam, thanks for trusting health care magic.
In my opinion you should get an ultrasonography
done because despite of a negative pregnancy
test you can still have a tubal pregnancy looking at your symptoms.
dont take it lightly and visit an expert radiologist
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.
