Spotting after Transfer #3

Hi all,

Looking for some reassurance today! I have some spotting pink and brown at 5dp5dt yesterday and some today. I feel like it is way too early for AF!!

I had spotting for the other transfers before Af came but this was more than a week past transfer.

I am taking baby aspirin and progesterone pessaries And the The iVF clinic said it could be due to the progesterone. Anyone had spotting then BFP? Any words of wisdom? I’m hoping it’s implantation bleeding but people say that’s a myth slash not common hahaha

Do I need to just wait it out? Argh waiting sucks !

Thanks in advance!
