Could I be pregnant?

Lisa • I`m 33 years old, I currently live in Lapine Oregon with my family. I`m a sweet person, funny, kind and loving. I like to laugh and stay away from drama as much as possible.
I was supposed to have my period March 1st. So far I'm 8 days late. I have polycistic Ovarian syndrome and I've been on Metformin for four months with regular cycles until now. Is it possible that I could be pregnant?
