Has this happened to anyone else!?

Hi ladies! Got my BFP on Wednesday of this past week. Tested again Thursday and still positive. By my LMP I would be around 6wks so my OB went ahead and got me in yesterday. My urine test there was completely negative!? They did a blood test and my hcg was only 55. They think I am a lot earlier than 6wks. I’ve taken multiple tests since then and they’re all positive! So confused. I did ovulate late...either 11/21 or 11/21. What do you guys think??
