FTM confused about what I'm feeling

Luisa
I got a really bad attack of contractions at 30 weeks...lasted two days straight and needed to be hospitalized bc I was already starting to dilate.  Contractions stopped with meds at hospital and I was sent home, ordered to stay hydrated and rest as much as possible.  That's what I've been doing since and was feeling much better until tonight.  Sudden onset of Braxton Hicks but it was one long contraction that wouldn't quit for several minutes when suddenly I started getting very sharp pain and pressure in my pelvis.  Baby was already head down and very low at 30 weeks when I was hospitalized, but could this be her dropping even lower?  Or me possibly feeling myself dilate more?  Since I started contracting about 2 hrs ago she's been super active kicking all around, but I can definitely still feel her head in my crotch like it's pressing down.  Should I be concerned about early labor?  I just passed 32 weeks 😞. Anyone who knows what I'm feeling please help!
