Difficulty in emptying urinary bladder.

I m a 34 yrs old unmarried woman frm Kolkata. I used to take thyronorm 25 for 7/8 yrs but for 2 months I take thyronorm 50.I am also taking Lumia 60K Vitamin D3 capsules 1ce a week. BP generally low; period is normal; problem of constipation,smtimes I need to put strain to pass stools and smtimes feel a bit downward pressure in the area below lower abdomen.Feel weak now and then;get tensed very often.I did some tests in March,the results are:Marginally enlarged liver; cystic left ovary; uterine myoma(size 2.5×3.0 cm); 147.9 ml of residual urine in post void bladder.regarding last point- i hv difficulty in emptying urinary bladder that results in freq urge to urinate.initially i ignored the problem for 3/4 yrs but recently i consulted a doctor who prescribed urimax 0.4 and betheran 25 for this and advised to drink maximum 2L water/day.Due to unavailability of betheran,i am taking urotone 25.My question is whether the medication is right as I came to know that urimax0.4 is not for women.
