You know what, you're probably right Jane. Plus she did this cervix measurement abdominally which has got to be less accurate. Ok, done worrying now.
Yikes, sorry you were in so much pain. Are you going to call the doctor or just leave it as you are feeling better now? I've had a bit of round ligament pain and it has been very painful but in short bursts. At 30 weeks I'd imagine baby is really stretching you out at this point. Congrats on being in the 30's!
