Worrying.

Ana
First of all I have PCOS but I'm also on metformin. Now, yesterday my cervical mucus was egg whitey and a lot so I was confused cause I thought I had ovulated last week. My cervix is so high I can't even reach it. Now last night, I had unprotected sex with my boyfriend and he ejaculated inside of me it was a total accident he always puts on a condom idk why he didn't this time. Would it be possible for me to get pregnant? Also, usually a week before my period my breasts feel tender and they haven't felt tender at all. Its so stressful, we both do not want babies any time soon.
