This cycle I had sex with 2 different people once each,
the first was on the 3rd of May

and the second was early hours Sunday 15th May

I then tested on the 20th and got a BFP.

Am I right to assume that the father is the one from the 3rd of May as surely a pregnancy test wouldn't show up positive only 5 days after sex?

Hey OP! How dark was the test? But yes very unlikely to have a positive after 5 days

You are absolutely not going to get a positive test five days after conception

Yep no chance of a positive 5 days after sex
