I am 8 dpo and I am having very heavy boobs and I ahve noticed that my nipples are bright pink and they have bumps on them. Also, I noticed lastnight that my nipples were dark but today they are bright pink. I am also having some major heartburn and I am not sure where that is coming from. I am also having alittle bit of cramoing in my side and uterus.I know that progesterone can have the same signs of pregnancy signs so I am wondering if anyone can help me wiht this. I know that it is to ealry to test to see if I am but I just need to know some advice from someone. Thanks so much. I amnew here so I am hoping that someone can help me.
