FET transfer this week & spotting today

[Anonymous]

I'm on 5 units of Lupron (stopping tonight) and estrace, set for an FET on Wednesday. Just this morning I started some light spotting and don't recall this from my prior FET (though it's been a few years). I'll check in with my nurse on Monday, but wondered if this has happened to anyone else? I had a great lining at my check earlier in the week and, of course, am worried about shedding that pre-transfer. Any thoughts or BTDT comments would be welcome.
