IVF- 8dp5dt pink spotting


I need advice please! I am 8 days past my first ever embryo transfer. I am on endometrin 3 times a day. I just did my 2nd suppository for the day and noticed a lot of pink discharge on the applicator and tissue that I wiped with. Is this normal? I’m so scared I’m getting my period. I would appreciate any advice anyone could give me.
