So, this past week. I have been so tired, i dont think i have ever seen my boobs this big. They were sore/hurting at the beginning of the week and my nipples look brownish. I have been having head aches. I thought forsure this was the month. Beening taking tests, all BFN. AF is due tomorrow but today i started spotting. The spotting is brown and bright pink. Could this be implantation? Is it my period? Also this is the first month i have been using Premama. Am i out or is there still a chance?
