So to for about a week or two now my. Nipples and my breasts have been pretty sore.. I've been bloated and constipated on and off, my period was due to start today, well Tuesday and never came but around like 11 pm I had light cramps so I went. To the bathroom and there was nothing but like a watery pink color when I wiped now I keep checking and it's always the same but it's brown now.. No real bad cramping just light and a little nauseated, I have a pad on just incase and I don't really have anything in it at all besides a little dot of brown.. Is this just a delayed period or does it sound like implantation? I'm also on the pill so it shouldn't be but idk, it's just weird.
