Check your tests ladies

I was supposed to get my period today. I didn’t. I’m 6 months postpartum. I’ve taken a test every single day for the past 6 days (6days before missed period) all negative, not even the faintest line, nothing and they were all first response. Not even an indent....until I realized the expiration date on the pregnancy test box when I was throwing it away. It was expired last week..funny because I purchased that box last week from target. When my period didn’t show today, I went back to the store and got a new box and I made sure to check the expiration date this time. Low and behold here are my results. God help me.
