Symptoms

Does anyone else here think they there should be an option to explain symptoms or is it just me? I have had a backache and nausea for 3 weeks now and none of it is related to my period or the possibly of being pregnant. I have to have my gallbladder out on Wednesday and that's what is causing the pain and nausea, but Glow keeps telling me to take a pregnancy test. I haven't been able to have sex in a while because I have been in so much pain. Maybe it's just me but I'd like to be able to put why I'm having the pain and nausea (if I know why, anyway).
