Hi, so my cycles are usually 25/26 days my last period was 4th jan making today cd14. I just took an opk and it’s lookinh like either tonight or tomorrow I will have my positive. However based on my times it looks as though an egg will never have the chanced based on that there will only be 10/9 days to fertilise 
I .did take b6 And this did lengthen my cycles to 28 days but I stopped taking it as It felt unnatural and I already have a DD
