Is it a false positive?

Ok so I was supposed to have my period on the 15th of this month and me and my other half had sex around that time & days afterwards. So for the last few days I been super nauseous, moody, & eating like crazy. So I decided to go and get me some poke(raw fish) & rice..(ya ya ya I know it’s gross but I’m Hawaiian it’s our fav😏). But anyways last night I decided to take a PT and it came out positive. But I think it’s a false positive because they say when u eat protein it can give u a false positive..so I’m not sure if it’s true or not.. but my other half was super happy cause this will be our 2nd child if I am pregnant.. so can someone help me with answers please☺️ if I’m pregnant that’s awesome and if I’m not then that’s fine too.. ONLY GOD CAN TELL US WHEN WE ARE READY!☺️
