PP hair fallout

Have any of you experienced any hair fallout PP? I'm 3 months tomorrow and just now started have terrible fallout. I was noticing my hair all over the house and when I showered handfuls came out! I thought that if it were PP hair loss it would have happened before 3 months. I just hope too much doesn't fall out. ☹️ I've been growing my tailbone length hair for years and now it's looking like I may have to cut it or at least get some layering.
