I just saw my high risk ob earlier today. No more than 5 minutes after leaving his office, I started to experience pain (not terrible..more like non stop cramping) in what I think is my uterus and a little bit in my lower back. Its lasted about 5-6 hours now. I did take 2 tylenol but its not really any better. I've had some twinges and a little bit of pain before but it usually only lasted a few minutes and then it went away. Have you guys felt like this when you've had RLP?
