Hi, I recently removed my IUD(paraguard) back in March. I had unprotected sex on 8/6/14. my period ended on 8/5/14,. I have been feeling light-headed, headaches, overwhelming feeling of nausea but no vomiting. lower abdominal cramping. white milky discharge no smell. trouble sleeping I wake up around the same time every night and its hard to go back to sleep. Could I be experiencing symptoms of pregnancy so soon? I have taken a pregnancy test but it may be too soon to detect. please help?
