little tiny lumps on my nipples?!

hey ladies I've just started to notice these little lumps on my nipples and I'm almost 3 days late for my period, I also just Googled it and it said that they can go red/pink if you are pregnant or breastfeeding, and they are pinkish. so my question is if any ladies have experienced the same thing and ended up being pregnant? I'm ttc and it would be such a blessing for me and my SO if I were to be pregnant. any insight would be greatly appreciated thank you ladies :) 😘
