help? advice?

when i was 18, still in high school&living with my then boyfriend, i found out we were expecting our first child. the day i saw those two pink lines, i cried. i was so scared, yet excited at the same time. wanted to do everything possible to give that child the life that he/she deserved.
when i was 6wks, i started spotting. went to the ER, they treated me like i was an idiot...the ignorant nurse told me "it was normal to bleed". they performed an ultrasound&when they got the results back, the dr. told me that i had a "tear in between the uterus&placenta". he noted that there was a "20%-40% chance" that i could miscarry. i'd like to know where he came up with those numbers.
i received very poor ob care. they treated me as if i was going to be another teenage dead beat. when i was 22weeks, my water broke&they had to deliver my daughter. they didn't bother putting her in an incubator, and told my then boyfriend that she had 10, maybe 15 minutes. she ended up living for 1hr2mins.
june 29, 2008.
people told me that i was NOT a mother, and spread horrible rumors about me.

i had my second daughter in November 2011 at 37weeks due to the amniotic fluid leaking(from a tear or something, i supposed). the pregnancy was uneventful&went well. *different father than my first*

when she was 3 1/2 months, i found out we were expecting our second child together. i knew something was wrong the entire time, same horrible feeling i had with my first. my ob kept telling me everything was fine. we learned we were having a boy&couldn't have been happier. at 25weeks(September 2012), i began hemorrhaging from an abruption. they had to put me completely under for an emergency C-section (because there was a "chance i wouldn't make it")&received a blood transfusion. apparently, the placenta was extremely calcified. my son had complications due to his extreme prematurity&lived for 2weeks. it was the most heart wrenching, stressful two weeks of my entire life.

i'm currently 9weeks pregnant with baby #4. they did an ultrasound to determine my due date two days ago. there is a "small bleed" between the placenta&uterus. my ob said that he has seen this in other women and the outcome has been fine, but because of my history i need to see a high risk doctor. tomorrow i have an appointment with a maternal-fetal medicine specialist&i'm scared to death...

I am so so sorry u went through all of that I couldn't imagine. I hope all goes well tomorrow, I will keep my fingers crossed for u.

I don't have any help but I wish you good luck and hope everything goes great .... It seems like you've been through a lot

I wish you and you're baby well 

Hope everything turns out well for you guys.

Wishing you lots of luck! Sorry you went through that. ):
