Stretchy discharge? PLS HELP! 😭

Good afternoon y'all!

I've just had my first ever transfer last week and have been on progesterone pesseries since a few days before. I've had the typical nasty thick discharge from them but this morning i also have stretchy brown discharge too. I'm not due for my period for another week. I'm really worried y'all 😭😭 i feel like it's definitely going to be negative. Anyone had this? Were you successful or no?
