I need yalls help.. Wth is going on with me

Okay, so some of you may/may not know my story. Last month I had a chemical. Was horrible. This month I got a faint positive at 6dpo, 7dpo, 8dpo and 9dpo. It wasn't getting stronger and by 10dpo it went away. I went to the dr office on Monday (11dpo) now yesterday and today (14/15 dpo) I am getting positives again. Wtf is going on!? Dr urine test was negative they drew 14 vials of blood to test for everything under the sun including HCG but the results aren't back yet. Can anyone have a clue as to what might be going on? I'm going crazy here. AF was due yesterday and I'm not even cramping.
