Period is odd this time around.

I thought I could have been pregnant, had a bfn twice. AF was due on Friday but absolutely no symptoms. My boobs were slightly soar the other day for like an hour. No real cramping, and my mood had been fine other than the other day when I got into a fender-bender (thankfully not my fault and no one was injured) I saw bits of pinkish, tan stuff after I went to the bathroom yesterday, and this morning I had slight bleeding when I went to use that bathroom, but there was nothing when I wiped, and nothing more through out the day. This hasn't happened before kinda confusing.
