Spotting after transfer?

Queen 👑 • Second FET success! Soon to be mama to boy/girl Twins 💖💙

Later today will officially make 8dp5dt. Tests have darkened so much from yesterday to today.. its been the most noticeable change in 24 hours since I got my first BFP at 4dpt... but this morning I had the faintest amount of pink discharge. I’ve been cramping but it doesn’t really feel like my period is coming, its more of a weird bloated and stretching/twinging feeling. Has anybody else experienced this and had a successful transfer? Specifically the spotting? Freaking out is an understatement!!!! ☹️ I feel like I can’t win 😔
