Hi, i am on tegretol for epilepsy . i am wondering if it would affect a home pregnancy test . i also have the implanon , which is now kinked. and i was told tegretol reduces effectiveness of implanon to 58%. i feel sick mostly all day and night, but it is most noticable after i eat. although i havent thrown up. im constantly tired no matter how much sleep i have. and sore breasts too. i have done countless pregnancy test but all come back negative,
