Hello mam, thanks for trusting health care magic.
In my opinion do your urine pregnancy
test which if negative get a pelvic ultrasonography
if everything is normal then wait for next cycle in case abnormality persists visit a gynecologist for opinion because it can be your perimenopausal symptoms which may be related to some hormona;l disturbance.
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.
