Mucus Plug

So, I lost my mucus plug yesterday (34.5 weeks) and once it happened I started having to pee every 20 minutes or so. Today I've been having to pee every 10 or less minutes. I'm not having painful contractions, but my little guy definitely is not moving nearly as much as he normally does. Is it just because he's so low in my pelvis? My entire lower abdomen feels sore, even to the touch at times.

Also, I know this doesn't really mean anything, but even though my stomach is measuring on time, he was measuring ahead. Do you think he's growing too fast for my body to keep up?

Thank you!
