I took a test on december 21 which came up positive. Ive taken several since then and they are all negative. I still wasnt convinced so i got a blood test and that also came back negative. I had some bleeding for about 4 days about a month ago. Im having some preg symptoms also. ive been told that false positives are rare, so im just so confused. if i am pregnant i would be about 10 weeks along,,if im counting right with my last real period. my drs wont do an ultrasound cuz it would be a waste o f their time since the blood test came back neg. I know thats the only way Ill know if I am or not..well at least until i start showing..so what the heck do i do?? i need to know!! do you think that its even a possibility im pregnant at all?
