What does this sound like mummas?

Hey,

So I’m only 15w1d..

Sometimes if I’ve been sitting for a long period of time when I get up I can stand up straight because my lower back and legs get this really heavy horrible pain.. I wouldn’t describe it as a shooting pain...

The back of my legs tingle and hurt a lot I struggle to lift myself off the bed/toilet or whatever but I thought surely this would be something I would experience LATER on in my pregnancy not already everything just feels so heavy and it feels like my legs are just going to give way!?

Is it sciatica or? I don’t know it’s really hard to explain but it’s worrying me that if it’s this bad so early on whats it going to be like in another 15 weeks...

Thanks for reading :)
