Help please lol

I was a virgin before I got married. Now that I’m married to my wonderful husband, we’ve been having a lot of sex this week. Sometimes without any condoms because his pullout game is good. When he pulls out, it takes 30 seconds for him to cum so I thought maybe I’m fine. But last night and today I’ve been feeling a little sick to my stomach. And told his mom about it and she said that being a virgin for so long, I can get pregnant so much easier regardless if he pulls out. I’m really nervous, I haven’t taken a pregnancy test because I’m not home yet. Could I be pregnant even if he pulls out ?
