<snip>Bella--please post what you did w/NPC, Vitex and anything else--v. curious.!
The vitex, I got from my HFS in tincture form. I believe this is more potent than pill form. I took 40 drops 3x per day. I started last cycle, on cd8, and I O'ed cd 16 - about 5-8 days earlier than I had been Oing. So it worked that quickly. I didn't notice any issues with my milk supply, either.
The NPC, I bought an organic one I found online called Oasis Serene. I started it at 3dpo - you need to be charting imo to confirm you have O'ed before you take it. I use 1/4 tsp 2x a day, in the morning and before bed. I rub it into my arms, thighs, abdomen, chest. You should alternate where you use it, and stop it if AF arrives.
I am continuing my vitex and NPC and will probably use NPC most of my pregnancy as DS was born at 36 weeks, but this is something I will discuss with my midwife - she may want me to stop it. I don't remember when I will wean myself from the vitex, probably around 14 weeks or so.
