Hello..Carefully going through your narration puts a few differentials in my mind , you should undergo Transabdominal ultrasonography
to look for any lower abdominal pathology including pregnancy
, you can also do a urine pregnancy test yourself to rule out that. Please get your thyroid
hormone level check because your narration is favouring its altered state. As you are having urination problem get your urine test done, you might be having urinary tract infection
,but the most important thing is to look for any pathology in uterus(especially to rule out pregnancy) and your hormone level as you are complaining of amennorhea sine five months with weight loss
which is very likely in altered thyroid state.
