my nurse said you can be in early labor for weeks and i feel like i am... ive had little contractions but only one night but cramping all day everyday for at least a week and now i feel like hes touching my hips,feel a lot of pressure downward, and ive been really sore down there(like a sore muscle ) now tonight my hips have been cramping and so sore. could this be a sign that labors just around the corner? im really uncomfortable but i dont wanna run to the doctor if theres no need. i have an appointment thirsday though and im gunna ask her to check for dilation for sure.
