Ok, Well it's been almost three months and I have taken 4 preg test, and there all saying negitive. I am not sure really what else to do here, my friends suggest I should take a blood test, because I could be or there could be something else? If I am not I would like to know whats causing the sore painful boobs, eating way more, gained bout 7 pounds, lite nausea in the evening, mid day, no mornings. I'm tired all the time, but yet no period, I am fairly a healthy person, I don't change anything in my diet drastically, and there has been no extreme high stress levels, and honestly that has NEVER affected my cycle. I am not sure what it is going on, I am worried, but I am not worrying to the point to delay it any longer. Please help!! Because everyone including my boyfriend is convinced I am. I was pregnant twice before, and the first time I had no symptoms at ALL, and found out I was 4 months pregnant. I don't know what to do! ?
