last period was 3rd Feb. Between 29th Feb - 2nd march (3 days) I had what I can describe brown spotting now and again when I wiped and little tiny bit on underwear. I thought I was due to come on around that weekend as my periods are normally around the 28 day cycle. Still no period but have been having period cramps on/ off. All negative tests though so confused as to what’s happening! Have anyone had the same?
