BFP but now red blood :(

Chelsea • 27 • Baby Nicolaou on the way! • Very happily married! 💕

So at 10dpo midday I took a test... very faint line. I posted it and many agreed they saw it (i actually took 4 tests and all have been faint lines, not just the 2). I get up to test 11dpo and I wipe.... red blood. Not a lot, just on the toilet paper. But still very faint line. Is this a chemical pregnancy? Have any of you had red blood but continued on with pregnancy and darker lines? I have a feeling red blood isn’t good...
