Hi I did my pregnant test at home and it came negative should I perform again or is it enough?

If you missed. A period do a second, highly sensitive first voided morning urine test in two days. Or have a blood pregnancy test done.
It depends. There is just not enough information in your question to answer this. If you tested before your period was due then it was too early. If you tested after a period was missed and at least fourteen days after the sexual encounter then it is likely to have been accurate.
