Advice please?!

So last week I got 5 BFP's...(first time trying to conceive) The weekend I started a very light bleed. I took a test last night and couldn't see a 2nd line. My partner is convinced that I will get my positive if I re-take a test with FMU. I however am not convinced at all ☹ 
Have any of you ladies been through this and got your BFP? 
I'm feeling so down and crappy, part of me wants to take the test again just so I no for definite. But I'm so gutted as it is and the truth is don't want to believe it's really a negative ☹ I am not bleeding just brown discharge ☹
