Teacher: Now, understand the problem? Solve this instance: August 20 , 2008 I was definitely surprised yesterday when the doctor told me that the baby has already dropped into my pelvis and into a nice position for delivery , but now that I compare the photo from this week and last week , it's pretty obvious ! I had previously read that the drop is usually accompanied by relief from acid reflux and shortness of breath , both of which are still very present for me . But I'm not a very big person , and there's not much room for this still - growing kid , so it looks like I'll just have to tough it out for a few more weeks . 
Question: What may have caused your acid reflux ?
