Aching stomach

I’m 15 weeks pregnant and my stomach is hurting tonight 😬 I ate a little bit of a left over ice cream blizzard and I’m wondering if that’s what made me feel bad. I also took a Tylenol because my head was hurting so now my pain is masked and I’m trying not to freak out because it’s hard to pin point where the pain is coming from. 😔 I don’t think it’s the baby but I’m scared because what if it is.
