Husband came inside me while high?

So my husband and I talked about how we aren’t ready for another baby just yet, he always pulls out but last night we both smoked a bowl we don’t ever smoke just did it to try it and after he was all loving and we had sex during it he asked me if it was the time if I could get pregnant or not I told him I just got off my period a few days again I don’t know, and so he finishes inside me then later today I get the alert that it’s my first fertile day. Before all this in the car he was talking about what he would like our next daughters name to be lol. I’m so confused did he just do it because he was to “high” or maybe he wants a baby sooner I’m getting mixed signs.
