Is it possible I get pregnant

Lauren • Tue, Dec 15

So my cycle was the 22 and 23. I have pcos. I ovulated on the 7th and on the 10th I had egg white cm and lots of it. My husband and I also were intimate on the 10th. My next AF is expected on the 20th. I have been since yesterday feeling extremely tired, had awful breast sensitivity and extremely emotional. Things are just not adding up. Is it possible that it is AF or something else? Please help
