Happy but sad...

Happy to say we’ve successfully hit 11 weeks today but yesterday my doctor told me that he thinks this is a failed pregnancy due to my hgc levels that have been decreasing the past three weeks! We had a ultrasound 2 weeks ago that showed a heart beat of 172 and baby measured right on track but my GP is confusing me so much he sent me back to work Friday after being on bedrest for two weeks and now he’s put be out another three weeks I don’t if I should be happy that I’m at 11 weeks or sad that he thinks there is an impending miscarriage! I also had a second opinion from a doctor in Ontario who is a family friend and she disagrees with my gp opinion! I called every clinic in the city to see if someone else would see me but no one would! What would you all do? I’m not bleeding I only had brown discharge once every few days??
