Hey guys, I really need your opinions! I have been having so many pregnancy symptoms lately that it is ridiculous ! My last period started on aug. 2 and ended on Aug. 5 or it may have been implantation that I mistaken as a period ! It was a very very light one with mild cramping but it is now sept. 14 and still no sign of a period! Besides that I have to pee every 30 minutes to a hour, my tummy is getting bigger, I am gaining weight, major fatigue, sometimes nauseated, mild abdomen pain, sometimes lower back pain, baby barfing(small vomiting), nipples are sore and breast appear to be larger, eating a whole lot and getting full but the next hour and a half to two hours it feels like I'm starving and I am extremely thirsty ! On aug. 23 I went to the doctor and the test was negative. I went to the doctor again last Monday and had a urine and blood test and they all were negative ! I took 2 home pt's last night and one this morning and they all were negative. Please help me.. Could I be pregnant again?

Note : I have been pregnant before and I only had abdominal pain, frequent urination, headaches !

Guys now I am having cramps like my period is about to start but it hasn't started! Please help !
