Nipple pain?

As

Hi!

So I’m not sure if I’m crazy or..... but the past couple of days (I’m 4 or 5 DPO I believe) my nipples have been SO sensitive. They hurt to touch and any bra is irritating. I also randomly feel like a pain from my boob straight into my nipple if that makes sense? Does any one know if this is normal or should I be concerned?!

Thank you!
