Please tweak and give me your opinion. Frustrated:(

Ladies..where do I begin. Yesterday, I had a super faint but there positive. I went and had blood work done, but she said it was negative. Supposedly my hcg was 1.5. I was so upset. Today, I just took a test and it was still faint, but so much more obviously positive(top picture and in the bottom picture, test on the bottom) has this happened to anyone? Idk what to think. Blood tests are supposedly more sensitive. Help!!
