Hi, I went to my OB/GYN and he told me that based on my ultrasound that my uterus is getting ready for me to conceive. He said that based on the white lines on the ultrasound I will be pregnant on the week of my period, which was suppose to start on the next day. He said that he will do a pregnancy test when I come back the next week. He also informed me that I had UTI when he did what I assume to be an internal exam. Anyway, I had cramps and spotted the day after meeting the doctor followed by a heavy flow which lasted for four days. Could I be pregnant or was it a misdiagnosis?
