How many times on provera?

Haley • TTC baby #2 going on 2.5 years ❤️

So I this is my 3rd round of provera(all in consecutive months) for ttc baby #2. I feel hopeless at this point after over a year of trying and no luck 😞 I have irregular periods where I’ll go moths of it being regular and then miss for months. Has anyone been on provera for this long or even longer? Any positive insight?
