I found out i was pregnant in june i was 5 weeks along then i had som bledding so i went to the hospital they didnt do a sonogram or anything they just did a blood test and said it was negative well my first 3 blood test were negative and i was 5 weeks. So when i went to the doctor after my miscarriage they didnt check me or anything and no sonogram well now its  August 3rd and im still felling sick and ive had no bleeding since the one time i went to the hospital my stomach is starting to get a little bigger and my breast so like rock hard and they hurt so bad and my feet are also swoling i am also tired alot more and have not had a period or anything what could be the cause of all this if my blood test was negative but they did not check anything else? Please could someone help me????
