I m now married.Now Last time I had my periods on 28th of April, 2018 for 5 /6 days. In the month of May I missed my period again. Now since the mid of June till now I am having continuos period bleeding (in the beginning it was kind of spotting). I visited another doctor this time.He did several blood tests like TSH, prolactin, complete haemogram, PT,APTT,beta HCG and a lower abdomen USG. And later prescribed me on 13/07/2018 with a medicine named pause 500 alongwith azithral 500, pantakind, cabgolin 0.25, eltroxin 50. But its been 8 days but my bleeding didnt stop yet.
