Anxious about AMH fluctuations over a few months, are these reassuring?

[Spinkyttc]

Hi everyone. I'm 30 and have become really anxious about my fertility, so I've had my AMH checked a few times over the last couple of years. My results have been:

• 29.5 pmol/L (venous, 2024)
• 28.7 pmol/L (Randox finger-prick, March 2026)
• 37.11 pmol/L (Newfoundland finger-prick, June 2026)
• 27.6 pmol/L (Randox QuickDraw, July 2026)

I know the drop from 28.7 to 27.6 is only 1.1 pmol/L, but I can't stop worrying that it's declined over just 4 months and that this is the start of my ovarian reserve dropping. The Newfoundland result being much higher has confused me even more.

I have a Mirena coil, but I've read mixed things about whether it can lower AMH slightly. I've also previously conceived naturally, so I'm struggling to make sense of all these results.

Has anyone had similar fluctuations in AMH over a few months? Would a fertility specialist see these results as reassuring overall, or would they be concerned about the slight drop? I'm really spiralling and would appreciate any honest experiences or advice. 💕

Why have you had it tested if you have a coil? Are you planning to ttc soon? My understanding is that the AMH is only a rough indicator of fertility - those readings are in the normal range so I don’t think that would be a cause for concern? Also lots of other factors other than ovarian reserve are relevant and I think I’ve read that AMH is often more relevant in the success rates of IVF than natural conception, but don’t quote me on that.

In all honesty it sounds like if anything is likely to be a concern for fertility right now, it’s your health anxiety. Are you getting any support for it?

Also to add - ovarian reserve starts dropping from birth! And there is a natural increased decline from your early 30s - that is expected. Plenty of people get pregnant in their 30s and 40s though. No way to know until you ttc! (And please don’t do that just to see how your fertility is, only if you want a baby right now!!)
