Im 31 weeks with twins. Ive never had so much trouble while working until lately. I end up in pain every time i work. My feet swell terribly. Granted they've cut my hours due to having to go to the doctor twice a week but it still seems to be to much. But i see other moms on here working 40+ hrs a week or working a factory job while being pregnant:(. According to doctors ill have these babies in about a month. When should i take maternity leave? I have it set for September 20th but everyone keeps telling me i wont make it.
