No withdrawal and pink bleed after 4 weeks

Hi everyone

was wondering if anyone has experienced the same? So I came off the pill approximately 5 weeks ago and had no withdrawal which is very unlike me. 2 weeks after I had terrible period pains and sore breasts to the point that I couldn't wear clothing on them or sleep properly. Week 4 and I am bloated, exhausted, veins showing on breasts and have had the most horrendous cramps back and front and super emotional. Yesterday I started losing what I'd say is pink blood which has now stopped after 1.5 days. I have taken 6 tests that have all come back negative. Feel like I'm going out of my mind as I feel pregnant or am I testing too soon to tell?Appreciate any advice or similar experiences as I do feel like I'm going insane!
