OPK as pregnancy test

🖤 Meg 🖤 • Mommy to Jayden; born on November 5th 💙💙

Anyone try this? I only have one pregnancy test left so I don't want to use it yet, but I'm 7 dpo now and my OPK is pretty dark ☹️ my ovulation was confirmed 7 days ago with OPK and temping, And I had a huge temp rise this morning
