22 Days Late, Could I Be Pregnant?

Mycah

I’m 22 days late and the last time I tested was 8 or 10 days late and they were negative. I get occasional pains in my left side and my mood swings are full force. Headaches have went away for the most part and occasional nausea but it doesn’t happen enough for me to try to pin it on something. What do you guys think?
