Hello and welcome to HCM
Distention of abdomen over a short period of time is of concern.
Such distention can be due to an ovarian mass or enlargement of some other viscera.
The first step to be taken is ultrasonography
of the abdomen and pelvis.
Further management can only planned after sonography of abdomen and pelvis. In case of mass arising from ovary few blood tests will help further.
You need to consult your doctor soon.
Thanks and take care
