I am 33 wks pregnant with my second child (14 years apart). I walked into the hospital at 9 cm dilated and had no idea I was even in labor (I felt damp in my underpants and was curious since it was not a show) when I had him. I have been getting extreme hot flashes with a lot of tighting in the belly. Come to find out, I am 2 cm dilated, 60% effaced, baby went from a -3 to a -2 in a day....two days ago they gave me a shot to stop the contractions - which I found out it was the tighting that were contractions. since that time, I have had two spells of what seems to be heart palvations, fever and flushed. I am still have contractions, but I only know that because I am now aware of what they are. Should I be worred? 4 days before my appointment, I had the same type of feeling. I did not know I was in preterm labor until my appointment (and the doctor found all that out).
