Hey-
At my 20 week scan, I was told that I had a low-lying placenta and even though it wasn't extremely low, I had to go back in four weeks to check it. The doctor told me that it was nothing that I had done and that sometimes these things just happen. She said not to worry about it and probably in four weeks, my placenta would rise and be where it was supposed to be at. And sure enough, when I went back for my second ultrasound, the placenta was no longer low and everything was perfect as it should be. So even though, I'm still unsure about why these things happen, I'm sure you will be fine! I wouldn't even think at all that it was something you did.
