HRT clearing up my nasal passages?

I just started HRT a couple weeks ago and I've noticed that my nose is the clearest it's been in my adult life. I always used to have some resistance when breathing through my nose and I had a perpetually runny nose, but basically the day after starting HRT it was much better and I even sound less nasally when I talk. I was just wondering if anyone else noticed something similar. I'm doing estradiol injections and oral progesterone.
