Questions about "natural" FET

What is the protocol with your RE?

I will call and ask for more clarification.  Does your RE still have a policy about being done with BFing before moving forward?

If you did and FET after having a baby did you need any further testing before proceeding? 

I think our RE has estrace/PIO(or inserts) and then they just monitor your normal cycle.  Do you have any monitoring with cycles before to see what your "normal" is?

How does the thaw work?  What happens if they don't make the thaw?  Do you just stop meds? Our frozen ones weren't anywhere near perfect (I pushed for freezing since they were still trucking along) but it wasn't my REs advice.  I don't expect them to make it past the thaw.

Thanks!

Re: Questions about "natural" FET

    We did 2 "natural" FETs.  I thought they were really easy since I h ave pretty normal cycles.  I have no idea about BFing but here is what we did.

    They made me have another HSG and hysteroscopy when I went back for #2.  I needed day 3 monitoring and then they just had me come in again 2/3 times mid cycles and when my follicle was 18 they triggered me (so I would not ovulate on my own).  Then my 3dt was 5 days post trigger and my 5dt was 7 days post trigger.  For my 2nd cycle they suppplemented me with estrace since my lining was a little thin and I was on progesterone both cycles.  They would have called that morning if they did not survive the thaw and at that point I would stop the estrace and progesterone.  It was great to not have to do BCP and lupron in the begining. 

    When are you thinking of cycling?????

    I take estradiol 3 times/day starting on cd3 so that I don't ovulate, but you would just monitor for ovulation instead. Then I start progesterone about 7 days before the transfer.You would start after ovulation is confirmed.

    I needed a SHG and blood work done before starting.

    I'm monitored for baseline on cd 3 and then weekly until the transfer. both us and bw.

    With the thaw, they pull more than you plan to transfer but if needed, they can thaw more quickly. If there are none, yes you can stop the meds.

    We did natural FETs for baby#2. We used the embryos created from my fresh IVF cycle for #1 and did single transfers. It took 2 tries.

    My protocol was this:

    1. Do an SHG (much less painful than the HSG) to check for possible uterine scarring
    2. I can't remember if I had a baseline blood draw. I probably did.
    3. Pee on a stick at home starting day 6 to monitor ovulation. This was especially important because on our second FET attempt I ovulated WAY early, and if I wasn't using my monitor we would've missed it.
    4. Show up at clinic every 3 or so days to confirm follicle growth and ovulation
    5. When ovulation is about to happen, do a trigger shot, just in case
    6. Begin progesterone about 1w before transfer?
    7. Begin antibiotics in preparation to transfer. This was I think 2 days prior to transfer
    8. Transfer day 7days past O.
    9. Continue P4 until beta

    I didn't take estrace. My lining was poor (it always has been), and my RE said that we'd switch to estrace if necessary if the second cycle produced bad lining. Thankfully second cycle was fine, and I got pregnant with S2.

    Thaw happens the day of transfer. I had 3 embies left. 1 in one straw, 2 in another. We chose to thaw the single one first, because it was graded as an AA prior to freeze. It had a 90% cell survival rate (my clinic considers anything over 50%) successful. We transferred. BFN. Second shot, we thawed the other two (both graded BA prior to freeze), since in a single straw you have to. One thawed at 50% cell rate, the other at 100%. We transferred the 100%, and that is now S2. We were asked if we wanted to re-freeze the other one and we chose not to. It was something we had NOT talked before the appointment, so we made a rush choice. Please discuss this situation with your spouse. My clinic will refreeze, re-thaw and transfer. They just don't have any statistics on success with re-thawed embies because there are so few sample points. We ultimately donated the 50% embie to our clinic, because they are also an educational & research institution.

    If your embies don't make the thaw, they will thaw more (if you have any more). Otherwise, you will stop meds and wait for the next cycle.

    One thing I wanted to mention. When we started our first FET cycle, my body from CD1 KNEW it wouldn't work. There was just something inside me that said it would be a BFN. I tried to push those thoughts away as best I could, because I didn't want to "make it happen" (if that makes any sense). And come beta day, BFN. I was apprehensive about doing 2 cycles back to back, but come that second period, there was something again inside me that said to go for it. And it was our BFP. It sounds TOTALLY hockey, I get it, but listen to your body.
