Definantly not one of my best days

If it's not one thing it's another. I woke up at 3:30am to use the bathroom and noticed I was bleeding. Like a heavy period. So of course I panicked and woke up my husband and rushed to the emergency room. They did an ultra sound and the baby was fine. At 14 wks the baby was measuring at 16wks and moving all over the place. The heart beat was great. But I was still bleeding. They sent me home saying it was due to a low placenta. ???? I emailed my OB and she called me and told me to get into the office so by 1pm I was on my way to the doctor again. Another ultra sound and same thing so I was sent home and advised to be on pelvic rest for a couple days and not to worry. So that is what I am TRYING to do. How do you not worry about bleeding like that during a pregnancy. I am so exhausted. I am thankful that the baby is okay of course. I tend to forget about my well-being and am only concerned about baby. The er doctors did check my kidney function and my creatinine was still 1.3 so its stable from my last check a couple weeks ago. Also the OB dr said he may have seen a little "bud" on baby :). We aren't going shopping just yet but I hope he is right
