Scary preggers problems

Hi all! I am new to this sight and am looking for some support and advice. I am 12 weeks along and about 3 weeks ago, I went to the ER because I started spotting. I was terrified, because over the last 3 years, I have had several miscarriages and the last one, last June was severe. (I was 17 weeks and the baby's heartbeat had stopped about 4 weeks before that. I carried my dead baby for a whole month and had to have a D&C to have my poor baby removed. It was horrible.) Anyway, they did an ultrasound at the ER and thank the good Lord, my baby was still alive. They also said I have a subchorionic hemorrhage.Ever since then, I have been spotting on and off. THen last week, I had a huge gush that felt like I wet myself. I ran to the bathroom and saw it was BLOOD! My body went numb and I thought here it is, the miscarriage. So, back to the ER I went and another ultrasound showed my perfect little baby, wiggling and moving and looking ascozy as can be. Well, I have had a couple more instances of the gushes, but the blood is wine colored (old) and quits immediately after the gush. There is still some occasional spotting, but it is brownish tan in color. My doctor told me that as long as there is no cramping and no bright red blood, that everything is okay. I am still petrefied. Has anyone else ever been throught this?I need some advice here. I am so worried that i am going to lose my baby that it consumes me. Please help a girl before she has a stroke from worrying.

yeah actually my friend had the spotting one night and the night night she felt sudden urge to pee and she ran out of the bathroom screaming take me to the ER and her boyfriend went into the bathroom and goes oh my god and he told me to look and i did and there was that gush of blood, we didnt flush the toilet but took her to the ER... they did like 5 ultrasounds on her and they said she lost the baby... well when we went home my husband and her boyfriend went to walmart to get her things that she was going to need for that night and when she went to the bathroom she came out screaming again and bawling and told me that her baby was in the toilet!!! so i ran in ther and there it was!!!!! i had to call my husband and told him they had to get home right away... and i explained it to him.... they are still trying to get pregnant, but are having no such luck! i pray for you that this doesnt happy anymore to you... good luck!
