Okay for the past 2 in a half weeks I have been stressed out of my mind in my whole intire life I have not been this stressed and since it started I have lost my appeatite and have not really slept well, I have been feeling really sick and just recently it has slowed down but everytime something stressful happens I get sick again. I feel faint also. I have missed my period. I am also constipated when I go to the bathroom and when I puke it's like im plugged from there its weird I have this pressure like feeling, My breasts are bigger and I also found a lump on one of them just the other day I also have the odd sharp pain in my lower left side stomach, I feel like my body is sorda comming back to being normal and i have this cramp like feeling like when you are about to have your period its like my body wants to have its period but won't let it, am I preagnant or is something else wrong with me like stress??
