I miscarried and it hasn't hit me

I'm 18, I'm single and I just miscarried. I had sex with my friend and we didn't use protection because I am on the pill. This happened then yesterday all of the sudden I had a sharp pain and I looked and I had bled. All the way through my pants. I found this strange because it would have been about 2 weeks early. I looked into it more and realized it could have been a miscarriage. I talked to people in planned parenthood for some answers (because my family is not supportive). The people at planned parenthood calmed me and gave me information about what to do next. I went to my gynecologist and she confirmed my fear. I don't think it has hit me yet but any ideas for when it does? Also any support would be amazing.
