Soo usually I wake up on my period? Today I have no sign of it coming....?? Which is very unusual for me...instead I woke up with all kind of weird new stuff going on with my body that I can't explain? My body can seriously stop playing tricks on me now! 🙅 Has anyone experienced lower back pain/pressure being associated with early pregnancy? Its in the area of my epidural sight from when I had my daughter? Because I have been feeling that since yesterday off an on? I understand that can be a sign of my period coming but I don't get that for my period? This is new to me other than when I was in labor? My body is seriously confusing me!!
