should I stop testing?

Sam • My rainbow boy arrived April 2018 💙💙. UK mama 🌈🇬🇧

So my last Af was 5th July and I ovulated on the 17th. Af was due yesterday and I already knew she wasn't going to arrive as I tested faint positive at 9dpo. I'm 14dpo today. should I stop testing now? I'm just so worried after losing 2. here are today's tests
