Brown spotting 6 weeks

Jo

This afternoon, I noticed some brown spotting when I wiped. This has continued and I’ve noticed some clots (still brown). I’m also having some cramps. I went to the early pregnancy clinic on Wed as I was having cramps and as I have endometriosis I’m high risk for ectopic. They saw a heartbeat but they measured me at 5 weeks 3 days (only 1.8mm crl) although by my dates I should have been 7 weeks. I’m getting so worried as I miscarried in January. Is this spotting normal? As it’s the weekend I can’t speak to the Dr or Clinic but I’m driving myself mad worrying.
