I feel really sick in evenings and just after i eat, i have to have a nap in the afternoon and my husband has noticed im really moody lately for silly reasons. My period isnt due for 5 days so there is a chance i could be pregnant, which would be amazing. But could it be depression?? My parents just broke up and i seem to be coping okay but depression doesnt just boil down to sadness, right?? HELP!!
