I lied about the tests...

My fiancé and I have struggled with infertility for a year now. I went into Dollar Tree to get some (5) pregnancy tests. I haven’t had my period in five months and because of that, I randomly take a test here and there, in hopes one will be positive one day. The lady at the counter said “You don’t think one will be enough” and kind of snickered. I blurted out “they’re for a pregnancy reveal.” The lady behind me in line started asking questions about what I was doing as a reveal. I lied again and said I was putting them in boxes and revealing it that way. Why the hell?!?! Why is infertility such a taboo topic? Why do women feel so uncomfortable talking about it?!?!? I just want to crawl in a hole and die right now. That is all.
