Math Word problems, skeets version

A 25 yrs old chic and doesn't seem to know her body. Last time I saw her was New Years day and she said don't nut in her because her period about to start. The chic said she fertile right before her period. Maybe it's me, but I know around day 14 of a chics cycle she usually fertile. Now this same chic had her period on 1/4 and wants to see me this Saturday 1/17. Is this chic fertile Saturday or if not then when?

There's website where you can go to find out this info.

Anyways, I ovulate about a little over a week after my period. I have my period now (last day) and according to the app I have on my phone, I'll be ovulating 1/21-1/26, with it being the highest the 26th.

Going based on my calculations she should be ovulating around that time.

Eta: on the 4th, was that the first day or the last day of her period, or in the middle?
Assuming the 4th was the first day of her period, and her cycle is 28 days, she'll be ovulating 1/15-1/20 (I looked it up on babycenter)
