Can the pregnancy test be wrong? i'm 2 weeks late on my period, my boobs are very sore and itchy and my nipples have got darker and sticking out, iv had cramps which I thought I was coming on but nothing iv also had sharp pain that comes and goes, iv been getting light headed and nearly passed out twice this week. Iv also had back pain and feeling sick but I done a pregnancy test which has come back negative. This happened to my friend last year with the negative test but when she went for a scan she was actually pregnant, could this be the same for me I'm so confused iv not had no stress or worries nore have I gained weight so there really is no other reason for my period to come any advice would be great thank you!
