34 weeks and dilated

Anyone else around 34 weeks and already dilated? Or was in a previous pregnancy?

I had to go to labor an delivery last night to stop contractions and they checked me and told me I’m 1cm dilated but still thick. This is my second child and I went into preterm labor three times with the first one but was never dilated this early. this is my second time going into preterm labor with this one.😶
