Af was due on the 17th and I keep pushing it back on the app. Well the farther back it’s pushed my ovulation week is push as well. So, I have absolutely no idea when I actually ovulated. According to this, if it’s right, we BD and used conceive plus fertility lubricant.

I took a test this past Monday and it was a BFN. I plan on testing again tomorrow morning, but I believe it will be negative again.

Anyone else’s calendar do this?
