Preterm labor

Sarah
So this morning around 2am I got really sick then started to have contractions we went to L&d at around 10am when they got really bad. They checked at around 1030 if I was dialated and yup! 2cm and 70% efaced. Still contracting and they checked at 130pm and I'm 3cm and 75%efaced. Has anyone had labor start like this then stop? I'm only 35 weeks. Worried about my little guy being ok...😞
