6 weeks postpartum, and ive been almost impossible to wake up for the last few days and then today i collapsed on the floor and wouldnt wake up until my fiance held me upright in his hands for a few mins while trying to wake me.. i was low on iron after having my son, and am vegetarian, could this be a continuation of that? theres a chance im pregnant again so would that combined with already low iron cause such intense sleeping spells? its quite scary when my fiance leaves for work and im alone with the baby knowing i could collapse and not be able to wake up to hear him cry
