2 Negative Test .....

I have been TTC with my husband for a short time and this month I just feel different. I swear my boobs have never hurt like this before a period!!! My calendar is saying we nailed it for consistency on all of of our ovulation days and my period was supposed to start on the 16th. I thought that it was a little early but 🤷🏼‍♀️. I’m experiencing symptoms. Swollen sore boobs, fatigue, weird dreams, frequent bathroom breaks. I took a test on the 16th and it was negative and took one today and still negative. ... what gives ?!?
