Vitamin D deficiency. Is it too late to start?

I'm 13 weeks pregnant and just found out I'm low on Vitamin D. The doctor sent me a letter in the mail to start on 10,000 IU. Right now I am taking 2,000 IU gummies along with my prenatals. I got the gummies before I found out I needed to take 10,000 IU. Not sure if that is enough but I'm on Google and found out Vitamin D deficiency can cause neuro issues. 😔 I am sad that I found this out so late and afraid damage has been done. What was your experience with vitamin D and your baby?
