My wife had a transfer of a 5 day blast FET 7 days ago. We took a HPT 4DP 5DT and it was positive. She’s been taking the tests each day since and they are getting darker. We’ve tested with FRER and Wondfo and have has positives getting darker on each brand.

This morning my wife went to the bathroom and everything was good, that is when she took today’s test. Then an hour later she went again and there was a dark brown/brown red discharge with mucus on her underwear and when she wiped. Since then there has been nothing more.

Has anyone else had this? Could it be implantation bleeding at 7 days past 5 day transfer, even though we’ve gotten a positive HPT since day 4?
