freaking out!

I had a marginal placental abruption at 28 weeks and it clotted. I was put on bedrest and have been blessed to make it to almost 36 weeks. I was having pain off and on but I have ultrasounds weekly to check my placenta and hey say it's fine. I had some light spotting but for me ANY spotting is a huge red flag. I told my doctor, got checked, and they said things look fine and sent me home. I do NOT agree with that and I want baby out now. My anxiety is through the roof. Maternal Fetal Medicine was very blunt and honest what bleeding at all could mean and I'm not risking losing my baby. How in the hell can I get a doctor to deliver? I know trust my doctors, but if it was the most terrifying experience almost losing him twice already and I'm so scared I'm going to if they ignore me now. I've had the pain and the spotting is when I wiped and by the time I made it to the hospital to be checked (I was 45 minutes away at my older son's doctor as he's sick) the there was no blood. I'm still freaking out. 😔
