hi. im a 19yr old female. ive been having long spells of nausea and vomiting for about the past month, alot of times due to a smell or when i was up in the morning, and also breast tenderness and nipple discharge. I had my period on june 11 but still took pregnancy tests because my mother had vaginal bleeding and low hcg during the first months of all of her pregnancys. i took three pregnancy test the last two weeks and took one again today because the nausea and vomiting was very prevelant this morning. they have all been negative.im not sure what to do at this point?
