I had my period last month on the 15th , it ended on the 21st. Ive been noticing my nipples have been getting darker but i shouldnt be getting my period till the 30th of this month. Should i wait or should i take a test now ? Ive very light and my nipples have nvr been this dark. Also its like a reddish brown, and there super puffy. Help please. Has this happen to anyone else ?
