Danielle • Praying for a baby ❤️✨
Ok so I have been tracking my ovulation for the first time! I didn't test to much in the beginning because they were negative so I waited till my fertile window I am currently in. And here is a picture of the tests would u have said yesterday's is positive? (The second to last) cd 18?? Or the cycle day 19? Which is today. These tests are so confusing please help! Lol
