I had my left tube removed on March 31 of this year and I’ve been having regular cycles since then and everything has been completely fine but this month as of 6 days ago I was supposed to receive AF and I haven’t yet! I’ve done 2 pregnancy tests both are negative, I’ve also been feeling nauseas the past couple days and very tired... what should I do? Wait and due another test or go get blood work done ?
