At 7 weeks I was referred to the EPU after having some light brown spotting. Had a scan and all was fine - HB seen. Am now just 11 weeks and just been to the loo and found the same light brown smudge in my underwear (nothing when I wipe). I'm still nearly 2 weeks away from my scan. Thoughts on whether I should worry or wait it out...? Feeling terribly sick right now...
