I BD 3 days ago, the app is saying i was 5dpo and when i went to the bathroom i had pink blood, i put a pad thinking my period was early. But my cycles are always on 28 is wasvonly my cd 21. The next morning nothing on the pad and when i wiped it was brown. Was it IB or is too early?. I have nothing coming out now is completely gone. Im so anxious to test but im holding off since is always negative. But this is new never happened before.

Ps. TTC 3 years.
