So I have been getting the p17 shot to prevent preterm labor again and I get to the dr only for them to tell me they don't have it there or at the other office, and then ask me if I have it with me ??? Like no??!? I come back every Thursday to get my shot not once have I brought it myself! So what happens if you miss two shots ?? One was bc of the hurricane and now this one bc they are stupid! Any moms on here have to take p17?
