Unsure of what is happening

First pic is what has been happening all morning getting no heavier and not coming out onto panty liner

I got a positive pregnancy test yesterday afternoon then got negatives ever since I woke up with very light pink spotting that has not gotten any worst and I have been feeling nauseous, bloated, emotional, super tired and sooo hungry I’m not sure what is happening and would like some advice please.

First test is the positive second is the negative.
