So I'm new to this but I am 6dpo and have tender nipples I know it's too early to test my period starts in like a week but then today I got this in my under wear a little brownish pinkish color and a little bit when I wipe also I've also been super nauseous in the evenings like actually throwing up as of today could I be expecting!?! Could that be implantation bleeding? Idk what it would look like? Help e thoughts thanks:)
