Weight to small???

Amanda 🐼 • Aiden James and Aubrey Ann 💜
Glow keeps telling me i am underweight. I weighed 114lbs this am and I am 5'8''. I have ALWAYS been tiny. I have weighted 110-120 for the last 10 years. But glow is making me feel like if i dont gain weight ill never concieve. Anyone have any insight???
