The amount (130 mg) shouldnt be a problem.
When your body reacted on the 20 drops as it did, I would take it as a hint you were overdoing things, to much in one go.
- We all have.
Dont worry; I swallowed one dropperful of Iodine
by accident once, eh twice actually, and recovered shortly by taking vit C. A little burning throat was all.
I have always taken my Iodine
with vit C, I know this is contradictive to most here, but it has worked well.
(only exeptions was when I had an infection or food poisoning coming up)
definitely increased my sex drive. It makes me more excited, unconcentrated and passionate."
-I hope you meant concentrated :)
-And your boyfriend want you stop taking it?? :))
About period irregularity; there may be several reasons for it. Like a lack of an element. Boron comes to my mind, needed to balance the hormonals. But; a warning, as this may increase your sex drive even more, give it to your boyfriend too, lol!
I would also concider Vit E, zinc. Iodine put a demand on your body; to act, do, perform better. When lacking one element or two, it could be enough for an unbalance. I have adjusted my dosages, types of supplements, on an of supplements, many times along the way.
In my case I regulated the periods from 21-23 days (hypo T sign) to 27-28 days. But it took a couple of years on iodine before it was back on track.
You are so young, doing so well; trust yourself in this. And keep asking for inputs here.
