My doctor at the hospital told me it's absolutely fine, but we need to remove it before going in for delivery so they can monitor oxygen levels through the nails. Just ask your hospital staff about their delivery day guidelines during your next visit.
I can barely bend down to see my toes right now in my 3rd trimester, let alone paint them! But yes, nail polish is totally fine to use. Just do it in a ventilated room so the strong smell doesn't trigger any late-stage nausea.
I completely understand how you feel, I used to search about every single cosmetic during my first trimester out of sheer anxiety! Yes, you can apply it, just try to use three-free or five-free brands that don't have harsh chemicals. Apply it near an open window so you don't inhale the strong fumes.
I totally understand wanting to feel pretty and pamper yourself during this special time. Yes sweetheart, you can definitely apply nail polish. Just choose good quality, chemical-free ones so you feel completely safe and happy.
Haan lagane me koi burai nahi hai, bas sasti wali thodi thik nahi hoti. Achhi quality ki lagana aur band kamre me mat lagana taaki uski tez khushbu se sar dard na ho. Apne haath-pair sundar rakho aur khush raho!
