This cycle is a natural FET for me. I had no meds before transfer and have been doing progesterone pessaries since transfer (and low dose aspirin, but I'll explain that below). Leading up to transfer, I just had b/w to monitor my hormone levels to detect O and then had the transfer at 3dpo. He never even did an u/s... As some have said above, the progesterone is probably not necessary, but won't hurt and gives a little extra peace of mind.

I'm also started taking low-dose (100mg) aspirin after transfer because I used low-dose aspirin after transfer for our last IVF (which gave us DD) and my Dr is a big fan of "we know what worked last time, so we'll do it again". I probably don't need the aspirin either (didn't take it for my last BFP and had no problems with implantation), but it is unlikely to cause any harm, so I have no problem taking it.
