Can a blood test for pregnancy be wrong?

so i went to urgent care the other day and took a pregnancy test came back negative so they did all my blood work and it came back normal i still feel like something wrong

Has anyone ever had the blood gender test done at 12 weeks and it be wrong? Lol I wanted another girl so bad the gender test says it's a boy

Have anyone ever got gender results from blood test and then took a ultrasound and the blood test gender was wrong?

So I did a blood test at my #13weekultrasound and results came back today and it’s a girl! Now I did hear mixed reviews on whether blood test can be incorrect or inaccurate for gender. So what do you all think? I’m still in disbelief honestly… have anyone results been wrong? I’m still waiting to confirm with the ultrasound in 3 weeks

Has anyone gotten the gender blood test and it was wrong? I’m only asking because I had my 18 week sono and they couldn’t see a “Peter” between his legs. Could I be the 1% that gets it wrong?

I am officially in my second trimester! I, however, am getting nervous that the blood test for Gender could be wrong!😅

I had a doctors appt 2 days ago I’m 12+5 rn and they did a blood test for the gender and to rule out if anything would be wrong with baby does anybody know how accurate the test will actually be For both things

has anyone took an early blood test for the baby gender and it was wrong? kind of overthinking all because of a tiktok.😅 i took a blood test at 9 weeks and was told a boy so everyone knows he will be a boy, also have some boy clothes but if the ultrasound tells me otherwise, i’m going to be upset.😅😅

HAS ANYONE HAD THE BLOOD TEST BE WRONG ON THE GENDER. MY BLOOD TEST SAID GIRL BUT MY HUSBAND AND OTHER 2 KIDS ARE STILL HOPING FOR A BOY LOL

Oh and mother in law taking about how the blood test and ultrasound pictures cud be wrong and I cud be having a boy and we already bought everything for a little girl really pissed me off…
