Ohh & I just wanted to add. My mucus plus wasn't clear, and not really slimy. It was clear, red, and a little yellow, and think. Kinda like snot. Tmi sorry. But everyone is different. Google pics ofmucus plug (warning if you get sick easy) to get a better idea of what to look for.
Sounds like your mucus plug. Which is normal to Lose. It can grow back, will probably fall out a few more times Befor labor. Nothing to stress about just tell your Dr at your next visit.
When to call the Dr...
*bleeding
*bad cramping
*water breaking.
Hope this helps!!
