Is this the "normal" time for this to happen if I'm pregnant? Does it happen this early? They've been getting darker since yesterday (or thats when I noticed it anyway) I'm 10 DPO today and got a glaring BFN yesterday. they are also sore and almsot always hard (my nipples usually arent hard unless im cold) but only my nipples are sore and not my actual boobs, I dont know if this is normal either
