Does anyone else have sorter cycles in the summer than in the winter?

[Fee6]

Hi
We have been trying to get pregnant for over 2 years. I use natural cycles for temp and LH sticks. I have been reviewing my two years of data today and can clearly see I have long up to 56 day cycles in the winter and down to 27-30 days in the summer. My LH positive always comes 11 days befor period. Has anyone else had a seasonal change. We are hoping to start IFV in the next three months.

Do you take vit d supplements?

Hi. I just take the prenatal multi vit. Do you think I should take extra vit d?

Yes. The 'rda' is probably half of what you need.
