I don't know when I ovulated but according this app it said I ovulated April 8th not sure last period was March 25-29 I tested yesterday but was negative at 19dpo. Well today when I use to the restroom and wiped it was pinkish super light nothing on pad and then when I went back to the restroom nothing on the pad or tissue could I have ovulated late and this be a chance of pregnancy. I was due on April 22nd according this app and nothing has happened yet what should I do! Experiencing small cramps and that's it
