So. I'm 32 weeks. And I have several issues with my doctor. But imgoing to refrain and just talk about the one I'm most upsets about. 
So I have placenta previa. Since 20 weeks it was a marginal from what little he explained to me. 
So a few weeks ago he says ok it's now just a low lying let's make a schedual for a c section at 39 weeks. Ok. 
Then the next visit. Oh it's right there. We might have to go ahead and schedual you for 37 weeks. 
Today he rushed in , ( as normal, after I wait over an hour) he does the ultrasound. Says something to the nurse lady and then starts a whir of " bed rest , pelvic rest, don't be alone, and stay close to a hospital at all times" but gives me no explanation as to why, is something wrong? Should I be very serious with these orders? Should I avoid walking around? .... what is the danger here ? 
And then he orders me to come in next week for rounds of steroids to make my baby's lungs develope faster and says we might need to take him 36 weeks. With still not a word of why ? 
I mean I'm nervous and afraid and clueless as to what in the absolute fuck is going on. 
Should I not be sat down and explained to as to why these precaustiins are being taken? 
As to why my baby will be taken a month before his due date? I'm just shoved this information and not told anything else. 
And I'm so far I don't think I should transfer again. I've transfers 3 times this pregnancy 
I'm so frustrated.Â
