My chest stopped hurting 4 months in, is that normal??

After ~2 months hrt I noticed my chest started to feel tender/painful which I took as a good thing, it was completely expected and somethinf I can work around.

Now, I'm approaching 4 months but it's just kind of stopped? I dont know if thats supposed to happen or what but this was unexpected.

If it helps I am 2mg est/100mg spiro 2x/day
