I took a pregnancy test a couple of weeks ago, it came out positive, went to my doctor, took blood and yeaning test, got the results, came out positive for pregnancy, but I had started bleeding a week before the doctor appt, thought it was my peroid, but my test from the doctor still came out positive, was refer to the OB GYN, they took blood and yearning test and that came out negative with the range of 4, they tell me 3 and under range means not pregnant, and 5 and over range is pregnant, I came out a 4, so I'm inbetween positive and negative. I don't understand?? I have to take another blood and yearning test next week. Could you give me any advise?
