boyfriend refuses (help)

Katrice
So I got a false positive on a blue dye test and got negative on the rest and I got my period today which was on time like always and all the pregnancy symptoms stopped also but he refuses to believe I'm not pregnant even while on my period he wants me to take another test and yes I know you can still get you periods while pregnant but that's not always likely what should I do just take one to put his mind at ease???
