Need answers plz😞

Four days ago I took a clear blue test and it was very faint but I seen a positive, two days ago I took a first response and it looked negative. I've been feeling pregnant(very nauseous, light headed, my stomach is tight, and a few sharp pains in my uterus) but I'm not due to come on my af until June 4th. But yesterday when I went to the bathroom I say light pink and that happened twice then it went away. My OB is very popular so I don't have a docs app until June 30th. What do you all think is happening?
