Positive HPTs, Negative Blood tests

I'll try to make a long story short: After a few weeks of symptoms, (and a month after Mirena removal) I got 2 faint positives on HPTs. Next day I began cramping and bleeding heavily. Regular Dr. did a quantitive blood test and it said negative. She thought it was a miscarriage. After 3 more days of symptoms, I took 2 more HPTs (one was digital), both darker. I called my regular doctor, she said blood was more positive and I wasn't preggo. I didn't trust her, and went to a care center for another blood test...negative. That was 3 days and 4 more positive HPTs ago.
Anyone have any clue what is going on? I have other children... I feel insane that I don't know if I am pregnant or not. Thanks so much!

That should read *blood test was more Accurate*... darn my editing.

If you're taking anything that contains hcg it could be registering on those urine tests.

Thanks for the response, but Not taking anything. I have made an appointment for later in the week with OBGYN. but nothing seems soon enough.

You should see if you can get a ultrasound just to be sure
