I need some advice. Me and DH had unprotected sex leading up too and on the day i ovulated. I am now 16dpo and 2 days late for af but still getting negative results. I have been nauseated, matallic taste in my mouth, head aches, dull achy uterus and heart burn like you wouldnt believe. I have also been waking at 4:30 am on the dot with lower back pain, broke down crying at work because a blowdry didnt turn out as well as i expected (im a hairdresser) and i just FEEL pregnant though this would be my first.. is there something else this could be other then pregnancy? Help! ):
