If the sex on February 20 is the one you don't want to be the dad, and if you got a positive from a home pregnancy test on February 24, do not worry about Mr. February 20. That would be too soon for a pregnancy from that sex to register on a home test (or even to have implanted in the uterine sidewall). Mr. February 20 is out of the running unless you had sex with him before then.
no he was a one time but I had sex with the one in January 31 more so I know he is the father and yea it was a home pregnancy test and I knew it was to ️soon but thank you I feel better
Don't worry. An egg gets fertilized, then its shell clamps down to keep all other sperm out, and then the cells begin to divide, and it is not until they crack out of the shell (around day 5 or day 6) that it is even possible for the embryo to implant in the uterus. Not until that happens (up to 4 days later) does any hCG go into your bloodstream, and only when the hCG is in your bloodstream could you get a positive on a pregnancy test. Given that it was a home test, which is not as sensitive as a blood test, that makes the case even stronger for the guy on the 20th to not be the dad.
