So all day yesterday I was nauseous and couldn't keep anything down, around 4:30 ish started to get chilled and haven't been able to get warm. Have bad headache, lower back pain, tail bone and when I cough feels like I'm pulling muscles down there. Due between February 28- March 7. What do you all think??? Should I go to doctor, he is 2 hours away, didn't experience this with my other 2.
