I ejaculated inside of my girlfiend, Likelyhood of pregnancy please help

[Gregy]

My girlfriend and I were having sex first with a condom. I finished in the condom and then about 30 minutes later we had sex one another time and later that night we had sex without a condom and I finished inside of her. It was a few days after she ended her period and she takes birth control but her new order of birth control didn't come in till 3 days after.The story gets worse we were both high on marijuana... But she took them the entire month before. We are getting worried because she is experiencing nausea and has stomach aches in the mornings. Her breasts are also starting to get sore, we have had unprotected sex twice and that was the only time I finished inside of her.. But idiotically the second time was a few days ago. I pulled out right when I started to even get the hint that I was about to finish, please help thank you

It doesn't matter if you pull out or not. She needs to take a test.
