Is this the pill?

It’s month two that i’m on the pill for the first time. last night I was hanging out with my boyfriend and I didn’t want to kiss him or show him any kind of affection. and that’s not like me. I said something to him before i went to bed about how I’ve noticed this difference and i don’t like it and i think it’s the pill. he began to say I’ve noticed you’ve been less affectionate since you’ve started. has this happened to anyone else and is this normal? i want to go off for a little and see if it’s the pill and try another brand.
