Hi! Im 14 days late and have never been more than 1-2 days late before getting AF. Every hpt I’ve taken has been negative, I got a blood test done yesterday and it was negative. I’ve had nausea randomly throughout the day for that last week but no sore breasts or any other symptoms, and no signs of a chemical pregnancy. Could I still be pregnant and just not producing enough Hcg right now?
