HELP! I had unprotected sex on 18th July, but took the morning afterpill on the 19th. I had my period on 1st Aug but it was lighter than usual. It ended on the 5th, I had sex again that day. Since then I have felt sick a few hrs everyday and after every meal. I've found myself eating more bread than usual and nothing seems to be curbing my appetite. I'm suffering with constipation and I'm convinced my nipples are darker, as well as my boobs feeling heavier. My body temp is all over the place, boiling one min then freezing the next. Two nights ago I woke up with incredibly itchy palms (can't begin to describe what they were like, really painful itching) and a red burning complexion. I've since read this can be a sign of pregnancy. I had a metallic taste in my mouth last week which I dismissed and cramps which resembled period pain which lasted a few hrs, and I have had lower back ache too. I'm due on again on 29th Aug but I'm anxious.... HELP!
