does hcg have to be gone to get pregnant?

Does hcg have to be completely out of system before getting pregnant again? 
I miscarried on Feb 3rd and just took a pregnancy test (to confirm it's out of system...) and it came up super faint- like almost can't see it but it's there.
So does the hcg have to be out of system before getting pregnant?
