hello everyone.. so heres a question.

im 16dpo, my normal monthly cycle is 30days, and its now 34. took a test last night, before work.. confirmed by me, my husband, and aunt. was a Positive. Took two more when i got home avout 8 am. both very faint positives again. about 2pm, i went to the health clinic. They said BFN. I'M confused. what do I need to do now? im very sure my home test were postive, faint, but still visible.
