ok so i was doin some reading just incase i could be pregnant and i found out that inplantation could last up to 2 weeks well im almost to that point and my period has stopped now but i was wondering cause everything says how the area around your nipples gets darker, well i havent had that at all and they arent all that sore they feel a little heavier and everyonce and awhile they hurt to touch but thats it, so is that ok to happen or is there something wrong?

If you mean that an embryo can float around for up to 2 weeks until it implants, I think the maximum time noted in the scientific literature is that it might be able to last 7 or 8 days before implanting.  After that, if it hasn't implanted, it's gone.

Implantation does not last 2 weeks -- at the most maybe 2 days.  Some women have no symptoms at all, but very rarely will you have a full blown period if you are pregnant.  I will assume that you are obviously having sex, so I'm going to suggest that you get on some form of birth control AND use condoms OR just abstain altogether.  Heaviness could be them growing (you're not done yet) or could be ovulating, pre-menstrual symptoms, stress, etc.
