Quoting GrumpsMama.:" I had them checked though my pregnancy, and 6 months PP for WIC, they said everything turned out fine.. ... [snip!] ... had this problem since 15, I'm almost 21. & No, not underweight. I'm 5 pounds more then my ideal weight for my height "
Quoting The Doctor:" Hmmm. That's odd. But, I'd mention it again to your doctor next time you see them. <3"
