Over reacting boyfriend?

We’ve been dating for 2 weeks now & yes we done had sex 2 times. & he’s done told me 2 times that since this is ovulation week I needed to go get a pregnancy test. I told him why don’t I wait till I miss a period and he said that doesn’t always happen. We didn’t use protection, I swallowed, & I’m on birth control but he’s like trippin! & he told me earlier I needed to knock on wood 😂 this all started tonight because my mom called and told me one of my high school friends was 7 weeks pregnant and she told me she didn’t want another grandchild b/c she has one on the way. She said one is enough for now. But the other night he just came out and said it like i don’t even remember what we were talking about! Suggestions? He’s 20 I’m 18 btw
