Dear Nicole, I know they can tell almost anything from bloodwork. Cancers or tumors do not cause panic. I know what you are feeling, 2 months ago I absoultly convinced myself I had an ectopic pregnancy, even after 4 tests! Then I was certain I had ovarian cancer! Its funny how the mind can work. I had the blood pregnancy test and I finally told myself I was NOT pregnant. THe meds should be kicking in and you will feel better, I know they had a show about breast cancer on today, and I immediatly turned it off, I made a vow I will NOT watch shows I know will upset me, I have stopped surfing the net too, those things only hurt they do not help. What meds are you on?? If you do not mind me asking. If the ER was concerned they would of kept you and your family Doc saying its alright I am sure you are, panic can cause you to think the worst, believe me I know! Let me know about your meds and how you are doing. God bless, Debbie
