Paula - I'm so sorry that AF raised her ugly head.. Big hug for you...
Baby2bee - Good luck with your BT today.. Fingers crossed here...
Star bright - I had 2 natural FET's and on my 2nd one I fell PG... On a natural cycle your body does what it always does which is produce the hormones in your body incase the egg fertilises.. You still release an egg after you surge and basically your clinic will BT you to find that surge then put your FET back in at the time in your normal cycle that it would expect a fertilised egg to want to implant... Your body should be ready for this... My clinic did a BT to check my progesterone levels 2 days before TF just to make sure I could support a PG on my own otherwise they will supplement your progesterone to help... HTH... Goodluck and my DH accused me of being negative on my last FET because I was already planning the next Stim cycle and I fell PG... If our state of mind was all it took and had that much ofa bearing on the outcome of getting PG we would've all been PG 10 times over.. We protect ourselves mentally as best we can..
