LOTS of blood and cramping..... Restrictions, but baby is fine

Fallon
This is my second pregnancy and we had a scare last week. I woke up in the middle of the night and there was bright red blood EVERYWHERE!! No tissue, no clits just a lot of blood. I never had any bleeding with my first. Then the cramping came. My husband of course took me to the ER where they did numerous tests and two ultrasounds. Found a spot on my placenta that was hemeraging  that was about an inch or so. Our baby was moving and flipping and had a strong 155 heartbeat. Went though over 3 thick diaper pads in less then 4 hours! The bleeding decreased after two days and then went to brown and super light and ended after about a full week of bleeding. Now I'm on weight restriction and no running or any form of exercise. Besides being really scary our baby is fine and growing quickly and that was the first time we got to see Roo and hear the heartbeat.  Just wondering if anyone else has experienced anything similar and what did you do or how did you handle it?
