so i am about 10/11 dpo and i was feeling sharp pains in my lower left side aligned with my belly button pretty much also accompanied by an aching burning feeling in my back this morning, which simmered down after a few minutes and now it is there but only just so it is noticeable.( the side cramps) could this possibly be implantation? is it too late for implantation? also, all these "symptoms" ive been having, do you only feel those after implantation occurs? or can you be getting symptoms before? im so confused now. ive never felt these kinds of cramps before so i was getting excited. also, does it matter which side you get the cramps on? what is the difference from the left or right side?
