So I took a shower earlier and I noticed that a lot of hair was falling out when I was washing it. Then I got out of the shower and brushed my hair and a ton more fell out. Idk if its my birth control or what but I have very thick hair so I'm not that worried but I dont want my hair to be falling out. Anyone else experience this at 3 months PP?
