To all recent/veteran bfps : spotting question

[Thechosenone]

hello everyone,
I know some of you have done IVF and went through a lot and I KNOW everyone is different when it comes to their body and how it reacts to the meds and the ivf process altogether. but i do want to know what did you all experience.

This is my second ivf. This ivf we transfered two blasts. I'm currently 7dp5dt. I started spotting sunday a little and i guess b/c i was being too active. anyway it kinda led into monday. it was light pink and brown. i called my ivf nurse and she told me that this could happen, which i know it could. she told me it could mean a lot of things, which I know. i did rest and drink plenty of fluids. the spotting stopped. i didn't have this with my first ivf. also since 4dpt5dt i had cramping...kinda like af but not strong at all. it is continuing today. I just want to know for all of those who spotted and cramped was this a key indicator for you that you would get your bfp? again, i do know everyone is different. I just want to know how many of you experienced it. thanks in advanced for your answers.
