35weeks

Yesterday night i had the usual menstrual cramp again. On top of that, i also felt the pain that deemed to be like gastric but i'm really not sure if it was the top of uterus or gastric. It was pretty painful till i can't move in bed. The next thing i knew was i felt like vomiting but nothing came out. The call for LS was immediate and i ended up sitting on the toilet bowl for 20mins, literally urinating through my anus. I'm not sure if it's labour coz i managed to sleep through. Right now, i still have slight menstrual like cramp at my bottom of uterus. What should i do sia?

I don't want to go to my clinic and waste time....
I don't want to go there and be paranoid....

So i read books and websites. It said i could be in early labour which could last one to two weeks before the real thing. Hope he can wait till 36 weeks. I know my son wana be to give birth naturally to him and the only way he could do is to come early so that he's smaller.
