Could this be the start?

I’m 32 and half week, had a 34 week premmie last pregnancy however never experience labour or dilating as he was emergency section due to his health..

I’m having irregular very very strong tightenings, they’re there all day but nothing regular which is so frustrating as I’ve been in agony for a whole 2 weeks however hospital said they could defo see my contraction on monitor and feeling my belly I wasn’t dilating just yet and until that happens they couldn’t do much..

Today I’ve got period type pain in my tummy but since yesterday lunch time I’ve got very sharp, piercing and sudden pains top of my vagina..

I’m wondering if this could be the start of dilating? If anyone’s had their babies or have past pregnancy’s please tell me what you think regarding dilating etc

I’m waiting for my wife to get in from work to go up the hospital...
