What is the most possible diagnosis of the following condition?
Upon assessment, the nurse found the following: fundus at 2 fingerbreadths above the umbilicus, last menstrual period (LMP) 5 months ago, fetal heartbeat (FHB) not appreciated.

Hydatidiform mole -hydatidiform mole begins as a pregnancy but early in the development of the embryo degeneration occurs. the proliferation of the vesicle-like substances is rapid causing the uterus to enlarge bigger than the expected size based on ages of gestation (aog). in the situation given, the pregnancy is only 5 months but the size of the uterus is already above the umbilicus which is compatible with 7 months aog. also, no fetal heart beat is appreciated because the pregnancy degenerated thus there is no appreciable fetal heart beat.
