My last period was Jan 12th and is now 1 week late. Still no AF breast are heavy and bigger but seem to went down in size but still heavy. I been crampy which is odd for me for the past week and feel like my stomach is full or tight inside hard to explain. My CM has been very minimal for the most part and watery sorry TMI. I been taking tests but keep coming back negative. Is there still a chance or am I out?

All advise and positive thoughts are greatly appreciated ! 😊
