Decreased Pelvix pressure

Hello ladies, I’m needing some help. I’m currently 36 weeks and 2 days pregnant with my first child, so this is all very new to me. I’ve had some pretty bad pelvic pressure for about 2 weeks and my baby has dropped. I’ve noticed that the pressure has just mysteriously gone away. Is that normal at this stage? Every follow up for the last 3 weeks she’s been head down but could she technically still move into a different position? Sorry if I seem paranoid I just worry a lot cause I’m still shocked I’m even pregnant. TIA for any advice.
