odd smell every month?

Hi everyone 👋🏼 so this has been happening to me pretty much every month since my teens/puberty (I'm 23 now).. and I never knew what this was or if it is normal. Every month I my 😸 gets an odd smell. It's not exactly 🐟 but kind of like musk...ish. It's distinct enough I can notice it and only at certain times of the month. This is part of the reason I have <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> and track my cycle to see if it is a pattern but idk yet 🤔 ...it does not hurt or is uncomfortable at all (other than I'm paranoid everyone can smell it) so I haven't gone to the doctor is this something I should get checked out? Does anyone else experience this? 
Also yes I 🛀🏽 daily TY 💟
