You could try searching on "flight alerts" and set up 5 or 6 of them. You'll get a message when the price drops. There are differences between how the various ones work. Some are easier to set up than others.
I do concur with SK ARR about prices usually not dropping toward the end. It used to be true, but hasn't been for quite a few years. Especially if you are within about a 21-day window.
I also concur that more details about your particular flight would help people help you.
However, one oddity can be that prices seem to go up on weekends and then come back down. That can be a matter of the cheaper seats selling out on weekends, and then the airlines offering more after the weekend is over.
I hope you are using a broader search like Google Flights, plus the airlines themselves.
