I got a positive opk and positive clear blue ovulation stick on CD15 PM I was having very light brown/pink spotting and cramps which I've never had before

This morning on CD17AM I took another opk and it came back positive (i don't have any of my CB sticks left) I'm just so confused as my bleeding has gotten a little heavier and looks like fresher blood... really don't know what's going on could I still be pregnant (I have also taken a HPT but it came back negative) I just really need some advice my doctor doesn't listen to me we have been trying for nearly a year now for our second baby and I'm just upset and confused as to what's going on
