Ugh. AF is due today (Saturday). Took a test yesterday (Friday) and it was negative. No AF as of right now at 12:35am. Had some dark brown spotting 4 days ago, swollen and tender breasts and extremely tired but still got a BFN yesterday. I'm getting frustrated. Maybe I tested too early and should wait until Monday or Tuesday to test again since AF is due today? Unless I end up starting later on.
