my husband might be excited for no reason 😔

So I took a home test pregnany on Monday it come out positive but the line was every light & my husband made me take another one the next day also positive just alittle more darker. I have a 4mth old didn't plan to get pregnant, but my husband is super excited, I'm kind of worried because I have no symptoms based on my last menstrual period I am 5weeks, also I have bad cramping like if I'm gong to get my period. Is this normal???
