I appreciate your query.
Based on your history, it appears that you have not had your period for the past three months, apart from the slight discharge once.
Did you have regular monthly menstrual cycles earlier ?
If that is so, then pregnancy
is a very likely possibility.
You have had equivocal Urine Pregnancy Tests so far, hence please do not perform any more.
You should visit a gynaecologist at the earliest, for an examination and an ultrasound
, which will confirm your pregnancy.
It is possible that it is early pregnancy, or an ectopic pregnancy ( pregnancy outside the uterus ).. however nothing short of an ultrasound will tell you for sure.
Also, you are definitely overweight
, which also might be interfering with your menstrual patterns, in case you are not pregnant, you should definitely try to exercise, eat healthily and lose more weight.
If pregnancy is not possible, please rule out other conditions like PCOD ( polycystic ovarian disease
etc, which cause such abnormalities of periods.
Everything should be taken care of once you visit a gynaecologist for further treatment.
Hope this helped you.
