Latent labor

Roomes

Hope someone has experienced this,

Im 36+5 weeks pregnant, for last 5 days ive had basically what i can describe as period pains really low down,

They have been rather mild and on days mon-thurs they died off by noon,

Friday i had them all day and was alot stronger and about every 20-30 mins, i went to triage and they said i was 3cm dilated but that could have been from previous pregnancies, id say the pain is 3/10

Today i have them again same pain 3/10 and then at 3pm i had a pain that id say was a 6/10 but then the rest have been 3s,

Its not braxston hicks as ive had them together with this and it feels completely diff,

This is baby num 4 and ive never felt this with the others!

Im bif miffed of what it is???
