What to do

Je

My husband and I have baby danced my entire fertile window, We used Conceive Plus to even help after hearing success stories. He swears that I’m pregnant because he says he is super tired (so have I, just haven’t said much because I don’t want to Jinx myself), I’ve been experiencing intense cramping the past couple of days. I took a test yesterday and it was negative. What do I do? Should I wait until missed period?
