😓Freaking out. Not sure what’s going on.😓

Got my BFP Friday night with multiple sticks and a digital. Starting last night I had some light brown spotting only when I wiped. Today I noticed this spotting (pic below, sorry TMI) AND it seems like my second line has completely disappeared.😓 Some light intermittent cramping. Going in for blood work tomorrow. I would be 5w3d.
