<human>: Provide a brief overview of the text.

Hey everyone thanks for taking the time to look at this, I was hoping to get some advice on what to do for my girlfriend. 

First off, my girlfriend is on Implanon and has been for almost exactly a year now. Second, we always have unprotected sex but I pull out and finish on her stomach (except for this most recent time).

So we were at our new apartment and I have been calling people back and forth all day for apartmenty stuff when I finally get a break, cable guy just left, parents weren't coming over for 2 hours. So my girlfriend just looks at me as soon as I finish on the phone and gives me a look then says "I want to have sex". 

So we get down to business and she is into it WAY more than usual, I almost forgot I was fucking her because of how much she is moaning and grabbing me so I was just so focused on that and I felt like I needed to come but she was so happy getting fucked that I just couldn't tell myself to finish yet and well yea I did despite not wanting to. 

She immediately gives me the most "my life is fucked" face I have ever seen, it tore my heart in half the instant I saw it. She had her hands over her head and was shaking, then she started crying and went to the bathroom. Every time I saw her face it killed me inside because of the despair in her eyes. I went and got a plan b pill to help ease her mind but she didn't sleep with me yesterday and has been really distant and doesn't want to talk.

Basically I am not worried about her getting pregnant, I am confident 2 birth controls will take care of that. But I feel like I betrayed her trust and that is worse to me and most likely her. I just don't know what to do to make her feel better or if she won't until she has a period. Even then I don't want this to ruin our relationship.
<bot>: Betrayed girlfriends trust by cumming in her instead of on stomach, she has BC and we used plan b.
