I know you said you do feel some better right now. I just felt like I had to tell you that pre-term labor doesn't always feel like labor.
When I was 7 months pregnant with DD, I felt felt fine. No problems except the backache I had from day 1. I felt a little "funny" and a little like you, afraid to call anyone and seem like an alarmist.
I did call my best friend (hubby and I were separated) and she took me to the ER. Good thing. I was in pre-term labor and put on meds, a home monitor and bedrest for the duration of my pregnancy.
Thank God that little voice told me to CALL SOMEBODY TO TAKE ME TO THE ER, because the darling angel you see below did manage to stay put until 37 weeks with an emergency c-section.
Good luck to you, and God bless....please keep us posted!
