the only cramping ive experienced is on my left lower side during this whole pregnancy. it kind of moves around on the left side and it doesn't hurt. i am 4 weeks. i read that you should feel cramping on the right side and the middle of your pelvic area.. anyone just have light cramping on their left side? does this mean baby implanted on my left side? it goes away and comes back. also i have no bleeding or spotting
