29 Days Late

Jasmin

I am going out of mind, I am currently 29 days late, I have tested every other day but kept getting negatives, until Saturday mid day I took the bottom test and half a positive line shown so I took another test Sunday morning (middle test) and a faint positive shown so I brought some 6 days early tests today (top test) and its showing negative (I didn’t take until lunch time) I rung the doctors when I was 17 days late and I was told its not an emergency and that I could be pregnant just taking a while to produce HCG?? Has anyone ever experienced this??
