Hi I'm wondering if anyone can help me please, I was checking my nipples around about half an hour ago as you do 🤦🏽‍♀️😅 and came across tiny bumps on my areola on both of my breasts and I'm just wondering if this is anything to be worried about or is this possibly a very early sign of pregnancy I am TTC and around 4 dpo and I've never had this before.. any advise at all? Sorry about the pictures (tmi) but abit worried.
