No aunt flow yet!

I was due to start AF on 4/6 and have not started yet. I have had light spotting for the last 4 days. It has definitely not been anything normal for me I may spot 1 or 2 days but then I'm full on. Its been a light pink the entire time. No major sign, no cramping boobs hurt light back pain today. Im so nervous we have been trying for so long im scared to get my hopes up to just get knoced down again. The spotting is not all day either it may occur once in moring and nothing rest of day or once at night then nothing. Have been wearing a pad to be on safe aide. Testing on Tuesday if still have not fully started. What do you ladies like AF just teasing or possible BFP!!!!
