I had my first 3 day embryo transfer on October 23rd. We found out Wednesday it failed. I just got my cycle this morning and waiting on drs orderes for FET orders. Is there anything I can do to help this transfer be successful??

Also I noticed while on meds I never once got any cervical mucus but as soon as I started this morning I had cervical mucus. Is that normal??

Yesterday evening I had dark blood on pad only once and only on toilet paper after. But this morning woke up with pad having blood so I’m assuming today is day 1 or am I wrong?
