Sore ( o )( o ) At 5DPO... too early for this symptom?

[SarahMc]

Hey,

I am currently 5DPO and i feel that my nipples are real sensitive like they are getting irritated being in my bra IYKWIM.

My questions are...
1.
is it to early to have this happen if i am pregnant as it might not of even implanted yet?

2. When did you start getting this and ended up being pregnant?

I have other possible symptoms too but i am trying not to read to much into all of this, i am just curious.

TMI....
ohhh and they are really hard and "sticking out" the last couple of days

Thank you
