How long after decidual bleeding can you get bfp?

Decidual bleeding typically occurs around the time of implantation, which is usually about 6 to 12 days after conception. A positive pregnancy test (BFP) can generally be detected about 1-2 weeks after implantation, so you may expect to see a BFP approximately 1-3 weeks after experiencing decidual bleeding. However, the timing can vary based on individual factors and the sensitivity of the pregnancy test used.
