you do get little bumps on your nipples when you are preg and the also go darker if i was you go to the doc and ask them to do a preg test but they arnt 100% if it comes back neg then ask to have a blood test they are more accurate but you need to be more than 5 weeks for it to show up.
Good luck
on your breast when not pregnant,this isnt a sympton,the aeola normally gets darker later in pregnancy.a blood test will show up within few days of conception,as more sensitive test,a urine
thanks i do realise you get can have those little bumps but i never have them and i have read that it can be an early sign of pregnancy still no period so off to get a test in 2 days if hasnt arrived
