I was pregnant, I was.

I was pregnant yesterday, I've been taking test since I tested postive a week ago. Every test was positive every single one and I started bleeding today a little than a lot. I went to the hospital and they ran a test it was postive faintly she said my HCG was really low... they sent me to another hospital because there was no ultrasound tech there on the weekend. So I went to another hospital and the Dr. There did a vaginal exam and and pee test. She came in and told me you are just have a period your HCG is 23 your urine test is negative and it looks like a period to me.... I explained to her what happened and she said you are not pregnant I don't think you where how can a professional do that to you... I had the symptoms and two days ago I noticed the nausea subside the line was fainter this morning my breast weren't as tender as they'd been my "period" this thing I have is horrible it like watery slimy blood coming out everytime I move it goes through my cloths this isn't a normal period it full of clots why did she treat me like this? Why? I don't understand.
