hi guys im new here so not quite sure what im doing, i already have a 4tr old girl & lately ive been feeling irratable & low, i had posnatal depression after having my daughter and wasnt sure if i was starting to get depressed again, my fiance is convinced im pregnant again even though ive been having my period every month, i have been having cravings for a certain chocolate bar just like i did when pregnant with my daughter, im confused, am i just low from the pressures of life or could i be pregnant?
