Advice please?

Hi I’m currently 34 weeks pregnant and I’ve had SPD since I was 10 weeks. I’m always in a little pain but since I use a wheelchair now it’s not usually aggravated.

Earlier I was walking into my sisters house and as I stepped through the door with one leg I slipped and pretty much did the splits.. I felt my pelvis move apart and was in agony but now I literally can’t walk. Just wondering what I should do?! I’m worried that if I go to hospital they’ll just say oh it’s your SPD and I’ll waste a journey. Baby is moving fine :)
