I want 2nd opinions. Please.

No, I know I'm currently not pregnant. But I'm 99.99% sure I was. This is what came out of me after almost 3 weeks of bleeding & horrible cramps in my abdomen and lower back. I was having many symptoms before, my boobs were so sore I couldn't walk down stairs. I was throwing up. Craving things I never have before etc etc. But because I was on birth control I just didn't think it could be pregnancy. Then once this happened it all made sense. I went to the doctor weeks later. Unfortunately because I waited so long she said nothing would show up in blood work. She told me that because I was so young, I shouldn't worry about it. Um what ? Pretty sure you're able to get pregnant as soon as you get your period ? She literally took one glance at the picture and told me she didn't think it was a miscarriage because if I was that early along I wouldn't have been able to tell anyway. So now I feel COMPLETELY torn, I feel in my body & heart I know what happened. But at the same time she said it wasn't a miscarriage should I really even feel as upset as I do about it ? Tell me what this looks like to you ?
