Hi,I'm a 29 year old female and I'm a month and a half late for my period and have all the symptoms from dizziness to nausea mood swings the works but I've taken test and all came up negative except one that had a very dim line and very dark one .I had my gallbladder removed 5 1/2 years ago and was wondering if that could effect a pregnancy test? I could really use some advice.please
