I have never felt more confused.. please help

Lauren

Three weeks ago I found out i was pregnant. I took at least 7 tests and they were all positive (faint but definitely positve). I went to the dr 3 days later and she told me her test was negative and later my blood test was negative. She informed me my pregnancy did not take and I was probably having a chrmical.

Fast forward 3 weeks I still have not bled. Not even any spotting. My pregnancy symptoms never went away. My boobs are still huge and killing me and im bloated as hell. I took a pregnancy test last week to double check and it was negative... what is happening?? Could i still somehow be pregnant?
