How am I experiencing hook effect strongly at 5 weeks??

sv

I am only 5 weeks and 2 days I tracked ovulation. So… I had vanishing twin syndrome my last pregnancy (still broken over it) but these tests!!!!

First two are from the morning and the bottom one is after drinking so much water and liquids all day you wouldn’t believe me! So am I possibly having twins again? Or just really high hCG?
