Help! BFP and red spotting!

Kerrie
Hi ladies please can I have some advice!!
Got my first ever BFP yesterday (Saturday) on a normal hpt - not FMU so faint . AF was due on Friday - light pink spotting yesterday evening. At 3am this morning (Sunday) I desperately needed to pee so did another test - normal hpt and a digital. Pictures attached. However, spotting is now heavier and more red but still not AF. Nothing in knickers overnight just when I wipe. Really worried this is going to be a chemical. Any similar experiences???
Saturdays not FMU test
This mornings 3am FMU test
