I've been getting more menstrual cramps and it has started to run across my lower back. It's not a constant pain but I've been getting it here and there since Friday. More and more BH, but I'm told to expect that with twins. Of course I know what real labor feels like and real contractions. I wonder if this is gonna lead up to the real thing, soon. Since its what happened with my first born. I'm 4 weeks away from my c-section. So I really really hope I don't go into early labor. I feel I can make it to 36-37weeks. But then another week rolls by and there's a new pain. So I just hope it passes.
