Started Bleeding...ER visit

so last night i had a really big gush and thought we lost our little "starburst" i bled for about 20 minutes then started spotting. so since i couldnt see my doctor for a couple of days because of the weekend i thought i would go to the hospital just to ease my nerves and see if i had truly miscarried and so i was at the hospital all day yesterday and night for bleeding and they had to do an ultrasound and an internal ultrasound and they found a HEARTBEAT! i couldnt believe it. we thought for sure that we lost the baby with all the blood i had lost. so i want to thank everyone for there kind words and prayers cause they worked. we still have our little bean!!! i couldnt stop crying when they told me that. and our families are relieved that we still have a baby and now im going to be on close watch and the nurse was saying that i might need to be put on some sort of bed rest... thats going to be hard with a 6 month old. they said that i could have either tore something or was carrying twins and lost one but i had an u/s on the 12th and there was only one baby in there. so this little baby is pretty sticky! i just wish i knew why i was bleeding. but im so happy that the baby is still okay. its going to be a rough pregnancy i can tell. i want to thank all of you for all of your prayers and good vibes.
