I did 3 tests last week that came back -ve . I can't remember the date of my last period but i'm late now. My boobs are killing me which is always the first sign for me, plus the other day I had serious metal mouth like I was eating tinfoil! Also an increase in appetite. We have been using the pull out method since I stopped the pill and it's always been successful in the past. Plus preg tests have always worked before for me as well. But all these symptoms.... anyone else experienced -'ve tests then ended up pregnant?
