Hello - I'm just trying fenugreek at the moment.
Background: DD is 15 weeks, my periods have come back already (cries) and she sleeps from 8 til 8 (with a dreamfeed). I think the combination of those things has really lowered my supply, plus, she's simply getting bigger and needs more food.
For example: three weeks ago, I was waking with exploding and leaking boobs and could easily express 125ml+ from one boob in the morning. Now, all of a sudden, I'm lucky if I can express 80ml, and DD has got very fussy on the breast, and we do a lot of swapping back and forth from boob to boob.
So I'm pumping like a mad thing (would like to bf to 6 months if I can), and feeding her as often as needed in her wakeful hours. (Some trains of thought think that you can get a bit 'pump-resistant', but if you have a hospital grade pump...)
From what I've read (and this is just me browsing the medical sites I can find, rather than eg, forums), the main issue with fenugreek seems to be if you have, or indeed, might have, diabetes. It might also give you / LO some digestive issues and make you smell of maple syrup (I regard that as a plus, rather than my current off-milk smell =).
I chose not to seek medical advice. I've now taken 6 doses of 1/2 teaspoon of powder, with some milk. There's definitely 'something' going on, but that could also be due to more pumping and the fact that AF is on her way out the door now! I'll see what happens in a few days, and next month too.
