Pregnant with Implant?

I am currently on birth control with the Nexplanon. My boyfriend’s mother thinks I could be pregnant and I have all of the symptoms of being pregnant.

I also have been researching and found that there could be false negatives from the Nexplanon because it produces the hormone estrogen and would affect the result of a pee test.

I took the top test a week ago. And the bottom one today. I feel like I see a faded line on the second one but I’m not that sure.

Should I worry about it anymore? Should I get a blood test just in case? Can y’all give me y’all’s opinion?
