Hello mam, thanks for trusting health care magic.
In my opinion as your urine
pregnancy test is negative get a pelvic
ultrasonography and b
HCG testing because it can be an early pregnancy or worse ectopic tubal pregnancy and then visit a gynecologist with reports.
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.
