Hi
So my girlfriends period was meant to start on the 22nd, and it is now 6 days late. She has mentioned having sore breasts recently as well. I am worried that she may be pregnant, but we have not had sex. The thing that worries me is a week or two ago while messing around, I touched some pre cum and later fingered her (but I am unsure what the time period was and whether I wiped my fingers). I did not fully enter the vagina but I was within the lips of the vagina. Is she pregnant?
(We are uni students that just finished some exams so I thought it might have been stress but the sore breasts is scaring me).
She isn't worried, but how do I approach her about this?
