I got 2 girls pregnant! Can you help me?

Okay -long story short-, the first girl was my ex and it was unplanned. Well we "did it" and I broke up with her about a week and few days later. Then I hooked up with my best friend who's a girl and we did it too. I planned to propose with her later. Then she told me she was pregnant. I was scared but happy so I just proposed to her after she told me. She said yes. 2 days later my ex calls and yeah- she told me she was pregnant. It hit me light thunder. She told me to meet her in her apartment tomorrow. CAN YOU PLEASE GIVE ME ADVICE!?
