So I want to get lash extensions before the baby is born---and I want them to still be on when I'm giving birth. When should I do it? 36 weeks so they're definitely on, (but might need to be redone if they start shedding if I give birth at like 40 weeks) or 38 weeks (but if i go into labor before then I obviously won't have them). I'm not a makeup person but I'm having a birth photographer and I know having nice lashes would make me feel so much more confident.
