How bad are blue lines?

Christi

I’m almost 5 m pp with an IUD and my husband just got his vasectomy. I have been having the worst ghost cigarette type smells for the last two days. Husband says your having a stroke. My friend says your pregnant, I said f you. My Dr friend says Covid, tested negative. So I tested but I got this funky line. For a minute the test didn’t look like it was working and now I’ve got this?!? I took it apart in disbelief and maniacally laughing… the heck is that??!!!
