Shall i switch to Allopathy? Treatment?

I Started homeopathy medication for Thyroid 3yrs back. Doctor prescribed me that after 3 years i will have no need for taking medicine for thyroid. Somewhere after 2 years i did not see much positive results out of it. It was working like allopathy medicine only, it will work fine untill i take medicine and then again my TSH levels will shoot up. I was anyway not getting my periods on time, i was diagnosed with PCOD too. My doctor changed my medicines but even after months and months i did not get my periods ( i discontinued taking medicines out of frustration ). This demotivated me to take medicines at all. I will purchase medicines but i will not take them. I'm having second thoughts about homeopathy right now and I wanted to have opinion about this, whether or not i should change my doctor or switch to Allopathy for my treatment ?
