Spotting since ovulation

This pretty much happened last month and I feel like it's happening again....i think I'm going insane!

This is my 2nd month on letrozol and this time we did a trigger. It's been tested out since Friday. I've been spotting since Thursday and it is really starting to get to me...14 days past trigger is this Friday.

Very dark until today. No reason to wear anything (only on tp... maybe a spot in the undies.) We did the dirty yesterday and now the spotting is light colored and i could feel the pressure on my cervix.

The people at the fertility clinic don't seem to think anything is out of the ordinary... they only want to know when my period starts with a full flow.

I have pcos, letrozol days 5-9 and triggered at 18mm. Is this normal? Do i still have a chance at a bfp?

I just feel stressed.
