update on last weeks bfp. had some cramping and fainted yesterday - doc sent me to local hospital. had four positives (i know - i wanted to be sure) but was concerned as if anything they seemed to get fainter. hospital urine sample showed negative they took bloods and said not pg but doc made me do one with him and said positive. he says the pregnancy may be failing but defo am pg they say there isnt a pregnancy want meanwhile havent had period still nauseous etc what on earth - has anyone else experienced this. so confused and distressed and jsut want to know what on earth is happening. p/s used clearblue and both me and doc read instructions to the letter. been doc for v long time and trust him.
