Thank you everyone. I'm feeling better, although the whole day I felt like my head was heavy and slightly woozy (that's a word, right?). Friday morning I have some tests to do in the clinic where my doctor works, so I will definitely see if I can leave him a message or see him. It was probably a one time thing, but better safe than sorry, especially when pregnant. I am not hypoglycemic, but it can be anything related to my pregnancy (high/low blood pressure, gestational diabetes) or nothing. I'll definitely grab something to eat before leaving the house tomorrow!
