Might be silly but I’m 20 weeks, I’m laying here on my back and watching videos then all of a sudden I feel this weird feeling in my stomach, best I can explain is when you drive quick over a train track and get that feeling in your belly? Or when on a roller coaster and it drops? But I felt that, then instantly felt sick, and then all of a sudden a massive headache comes about.... what is this? 😢 anyone else had this?
