Test was taken just 5 mins ago.

I was away on vacation during predicted ovulation I didn’t track while away. I noticed cm was milky and thick I got home a few days later and my husband and I bd but I honestly think I was out of my window. According to this app says af is 6 days away. I’ve only been home a week today! My boobs are tender, have headaches on and off today and have Been nauseous since I woke up at 5 am! I keep telling my self it’s not possible.
