Is it too early?

Rachel

So my hubby and I haven’t been trying to get pregnant, we got married 2 years ago and just wanted some time of just us two. But always said if it happens it happens. Well I was 2 weeks late yesterday we did have sex last night but I pulled out the pregnancy test and those 2 lines lite up in no time. I’m really really excited but I’m just wondering if it only happened because we had sex last night?
