So I have been feeling very 'strange' all week, I held out and caved this morning and did a cb test. Reckon I'm about 11dpo. Need some reassurance is this nothing or is it a vvvf line I can see? Feeling unlikely that it's my month but I have just been so light headed, crampy, really bad lower back pain, sensitive nipples etc that I just had to test! What do you all think?
