Dry during sex ??

Ca

So I was having sex with my boyfriend yesterday and I noticed I just became so dry. I was enjoying it but I just wasn’t wet at all. Ik it might be tmi but I’m really confused about it. I am on the pill and wondered if this might have something to do with it. I’m still pretty new to having sex frequently so I was wondering if this is normal? Does it happen to any of you ? Or should I talk to my doctor about changing my pill.💞
