So another loss

VI
So I had another positive pregnancy test...last one was in July. But started to cramp real badly and lost it. When they did my ultrasound they also found a fibroid in there. I wonder if there's a connection. I'm sad because I got my hopes up. I wasn't far along but it still hurt. Also I am starting to think I have low progesterone levels because my periods are short and so is my luteal phase. Anyone have this issue. And what did they do for you?
