They have had me on progesterone shots since 16 weeks. I also have been put on procardia to help. The last 2 days I have had to be pretty religious on taking my procardia ( prescribed to me every 6 hours as needed) every 6 hours on the dot or contractions start up. If I take it they simmer back down but this has only been the last 2 days. Any one have this? Or just a pre term baby advise will help too. I'm not sure I'll make it to 37 weeks. Thank you!
