Ovulation 😨😥🥵😳

Clarrissa

So on the flow app it says I’m fertile the 8-14 and I ovulate on the 13th, on the first response site it says the 4-14 and then I checked another site that said 6-10 so I’m so confused. When should I take an ovulation test? ( we are trying the shettles method) so timing is critical. This is our first time “trying “ with both boys we got pregnant unexpected.
