So, apologies for length before I start. Period started 15th Aug, 27 day cycle. Monday had a positive clear blue digital on the fertility monitor. Tuesday I had a positive clear blue ordinary digital and a positive superdrug digital BUT negative line superdrug test. All done first thing. Today I went crazy and did the clear blue digital fertility monitor pregnancy test midday, then a clear blue digital and superdrug line test and ALL were negative! No spotting no period cramps. Terrible upper back pain which is very odd. Is there a hope I'm still pregnant? Did I test the wrong times? I will test again in the morning but really can you get 3 positives then 4 negatives and still be pregnant?
