Did you get sore boobs?

Before you found out you were pregnant? I mean I know a lot of women get sore boobs before their period, I definitely do. But they aren't really sore at all right now and it's due on the 5th. Last night I had brown spotting in my undies, like I did for my first pregnancy that sadly ended in a mc, and I can't remember for the life of me if my boobs were sore then! I didn't have any kind of spotting today, just a little bit of watery brown tinge on the toilet paper. I don't have much cramping at all, but sometimes I don't really cramp much until the day before or the day of my period. WHY DO PERIOD AND pregnancy SYMPTOMS HAVE TO BE INDENTICAL 😭
