Hmm, I was diagnosed with Vitamin D deficiency in October 2012. I think my number was like a 12 when 30 and above is normal. I immediately started taking 4,000 units of Vit D3 and got checked again in January 2013. In January 2013, my levels were up to normal by then. However, my doctor had told me to just continue taking 4,000 units. So I did and the last time I had my levels checked were about 2 months ago in October. My number was a 40. However, when I first found Gender Dreaming, I got scared to keep taking it b/c of it swaying boy so I had taken it every other day and then stopped it for about 3 weeks. However, I noticed my period/ovulation was weird so I went back to taking 2,000 units per day and that's what I've been doing now. I never really get out in the sun much at all. I live in NY and it's freezing here right now and I'm not a fan of cold weather. Even in the summer the heat can be too hot so most of the time I'm indoors with the central air on. I also work 3 days per week so most of the time I'm in an office for 9 hours a day. But to answer your question, my numbers came up dramatically from the vitamin D3, 4000 units per day after 2 or 3 months of taking it. I hope that helps answer your question.
I'm sorry to hear you may need surgery one day. That sounds serious! I don't think what I have is that extreme with being irregular. I really hope you feel better and hope that you will not need surgery. That stinks!
