Normally have regular 26 day cycles but now 10 days late and BFN. Had tiny amount of brown spotting around Day 26 and have since had some clear discharge (not enough to use liner). Been feeling extremely tired, ocassional headaches (don't normally get them) and had a few midnight toilet trips which never happens. My DH and I think my breasts look different but not sure if that's our imagination. Could I be pregnant if I'm getting BFN's 10 days after missed AF and is it too early to go to doctors for blood test?
