Super confused lots of hope

Rebecca
Went to the dr today. Home test Sunday night and Monday morning were positive I'd be between 4-6 weeks pregnant Tuesday I started bleeding, when I went to the bathroom. Went to the dr Wednesday and the dr said he can't say I am or not pregnant. My paperwork they gave me says I am. Ob apt for more blood work and and I'm sure more ultrasounds. 
Anyone else have this problem?
Any suggestions?
