Bleeding and possible positive test

Alyssa • 🌻💝🌻

I am 16 dpo currently AF was due on Sunday. Yesterday had twinge in my right side which has now turned into a pain. This morning woke up to spotting which is now heavier. Just took a pregnancy and ovulation test and I am so confused. I feel like I see a light line on the pregnancy test and the ovulation test looks positive too. Help, should I go to the ER?
