4dp5dt

Andra
Hi everyone 
I am 4dp5dt 
We transferred top grade blastocyst but I am worried that will not implant because of my high tsh.
Anyway I had last night and today ewcm ( more thick and yellowish sorry tmi)
I don't have  no symptoms apart from very bad af cramps.
Can you please let me know if anyone had ewcm and af cramps and end up with bfp 
By the way I tested yesterday 3dp5dt and is completely negative 😞😞😞😞😘😘😞
