Progesterone levels before FET

[KatBeCool]

For those who did FET, what were you blood progesterone levels just before FET or day of FET. My specialist says she wants above 12 and that there is no specified upper limit. But from what I'm reading, ideally you want it between 12 and 20, while some places say up to 30. I'm worried mine are too high.

I had my FET a few days ago and mine was over 100! It was at least 120. She said it was very high but that is fine as it just needs to be over 30. I'm guessing now thats not very normal but I'm not worrying as she said its fine.

@Rd12 ohh how I don't like it when there's no clarity. Like they want under 1 (or 0.96) for your baseline. That is clear as day. Why can't it be the same known range for the transfer? Fingers crossed for your fet to work!

Mine was 155 on day of transfer (was taking x3 cyclogest per day) - the clinic said this was the highest they had ever seen....Im pregnant with twins and part of me feels like this is what helped both of them stick

But this was our final transfer and I never tested on the 3 previous transfers so don't know if this level was normal for me or was a one off?

The clinic I'm with don't do any blood tests. Just saying to give a bit of reassurance that the level can't be super important if not all clinics even test it.

@seven201

Mine didn't as standard either but I requested it (and paid extra although only £35) to get it done as I was curious and we were down to our final cycle and I just wanted to know if there was something we hadn't checked that might make a difference and caught early enough ie on day of transfer I knew I could get extra progesterone in the injection form which might make all the difference

@ivfbeenbusy that's interesting. I had a fresh transfer (my first transfer) and 6 days later got my period. They think it was my progesterone levels suddenly dropping so I'm on lentogest injections (ouch!) and extra suppositories for all transfers since. I find it so weird how differently our bodies can behave.

@seven201 how can they think your progesterone levels are dropping or if the extra medicine you take is even helping without them ever checking? I'd demand some tests.

I guess because the dose they give me is so high and it didn't happen again (I've since had two FETs and my period didn't arrive early with those). I think they said something like blood tests don't help with the injections as it somehow doesn't show up in the blood test. Just writing that out makes me wonder how that is possible

I had mine checked on the day of transfer.
I believe there are 2 different measures in which clinics test
I know that American clinics like your levels to be over 10ng/ml
But most British like it to be 30 nmol/l.
They effectively are the same measurement, just recorded differently.

So on the day of transfer, my level was 27.8nmol/1 and my consultant put me on 25mg of Lubion. Up until that point, i was so positive about my cycle but when he told me that, i was certain it wasnt going to work.

Im now 24 weeks pregnant.

Im not sure that progesterone levels can be too high... i dont think thats a thing.

Good luck

@Aprilbaby21 mine is 80 ng/ml, which is 200 nmol/l. That seems very high to me so I'm really worried. I'm hoping it didn't ruin anything.

What has your clinic said? Im pretty sure there is nothing to worry about. Its only a worry when the levels are too low, but im not a professional so worth asking them.

@Aprilbaby21 the clinic said that there's only a lower limit but literature doesn't specify an upper limit. But if I read online, it's complete chaos. Some studies mention a range, others say it's fine when it's high, some say it's not fine.

Were you successful with this levels? I'm worried about high levels .

Hi all,

Jumping onto this thread as we have an FET Tuesday following 2 previous IVF miscarriages. Had a progesterone blood test today which came back as 40.8, the Dr said it's fine as over 30 but I'm catastrophising that it's still too low.

Wanted to follow this for any further comments!

Good luck to you all x

@VioletCookie I had a FET after a failed fresh, I bled 7dp5dt on fresh. I have naturally low progesterone as I spot between periods so although just before my FET my progesterone was 35 and clinic were happy, I pushed for lubion injections too. I just didn't trust my own natural progesterone levels and I wasn't absorbing pessaries as efficiently. I get hormonal headaches and felt the shift when my levels dropped the day before bleeding, had a blinding headache on the fresh.

The FET was successful, got a positive at 5dp5dt and I took lubion and cyclogest all the way to 12/13 weeks, and when I stopped them I got a private progesterone test to check levels and they were 1500!!!! I was so shocked as that's way higher than 2nd trimester, but the consultant at my midwife appointment wasn't worried, she said some women are on progesterone all through pregnancy to avoid MC or early labour. So I'd just had a build up plus the placenta was obviously providing enough for baby too! I'm now 18 weeks and still worry about levels daily 😅

@Imisscoffee2021 That's incredible, congratulations! I hope everything goes well for you 🙏🏼

I'm not really sure what to do, my partner is telling me not to stress but this whole journey has me so anxious! Since having the miscarriages we've found out I have Hughes syndrome, so I'm taking asprin and will start Inhixa on Tuesday. But both losses were really early, around 5-6 weeks, so I can't work out if that's down to something else. It's driving me bonkers all the over thinking and googling 😅
