BFP after mc?

Be
Had a mc March 27 and hcg finally got to negative last week. Had one period 2.5 weeks ago for 5 days very heavy with clots  hcg at that time was 12.  Two days ago started spotting and having very light flow.  Had implantation bleeding with my first pregnancy and this is exactly same. Took pregnancy test yesterday which was negative. Woke up this am with nausea and breast fullness/pain so took a pregnancy test again and I think I see a second line. Drs office basically brushed me off and said its too soon. What do you think? One of the girls at work saw the second line too.
