Contractions/Procardia/Magnesium

Chambree
I'm 21 wks 3 days and have been having contractions since 15 weeks. I had to have a cerclage and was out on medication for preterm labor and my contractions stopped. My doctor took me off at 19 weeks and I have been experiencing contractions again but they arent constant so I figured they were normal. Has anyone been through the same thing and if so any advice?
