i got my blood test done for nipt and gender when i was 13+5 days and they said tests not performed meaning the blood test was invalid due to low fetal dna. does this mean something is wrong ? they just said that it happens sometimes they don’t really know why which isn’t real assuring 😩🥺 i’m getting it re done this saturday and i’ll be 15+5 so i hope it goes through this time 🙏🏼🙏🏼
