Can Soy delay your period?

So I recently in the last 4 weeks have started to become obsessed with soy lattes. I probably have had one a day, some times two, 5 days outta the week. Bad I know 😞
I've heard that soy is packed full of estrogen, and has the possibility of effecting your menstral cycle. Anyone had an issue with this? 
I've taken a pregnancy test, it's negative. I feel the period coming on.. but nothing yet! Just wondering if this has effected anyone else? 
Thanks so much!
