sudden muscle weakness

I’m trying to decide what to do... I woke up this morning to the front of my thighs being extremely sore. I can’t touch them without yelling out in pain. They’re sore, they ache, they feel like they’re burning at times, my muscles feel so weak it’s hard to walk because my knees keep buckling, I need assistance sitting down & getting up... I cannot think of a single thing I did the last two days that would have caused such a thing to happen. My husband can’t think of anything I’ve done either.

It’s almost 9pm here which means all walk-ins are closed, my OB doesn’t open again until Monday (I’m 10 weeks pregnant)... so the only thing left is the ER but it’s really not an emergency... I’m just so miserable & it’s starting to freak me out a bit. Just sitting here my thighs hurt. I can’t get comfortable.
