Vaginal heaviness and suprapubic pain

I am 34 weeks today

i was having irregular contractions last night ( i have been having them for several weeks), today I worked hard and did 1 hour walk, i was having lighting Crotch through the whole hour with heaviness in my vagina, even though my baby is Breech but there's too much heaviness now i can barely move.

I have been drinking lots of water and did rest for a while but still no change.

there's no regular contraction neither any bloody show! What should i do? Should i just rest and see what happens or call my doctor?

P.S. it's my first pregnancy so i have no experience 😅
