Unsure

My husband and I have been trying for a second child since March. In July I had a chemical pregnancy, no period in August, had a regular cycle in September. On 10/11 I took a test at 7:47am(1st picture) and got a faint positive. A few days later I took a test and it cam back negative. So I decided to wait a little longer, and I tested again at 5:30pm(2nd picture) and there is nothing. I am currently 10 days late and I have had some of the early pregnancy symptoms. But getting no result. The 3rd picture is both tests(top is 10/11, bottom is 10/17). I was just curious if anyone else has gone through something similar to this. Thank you.
