Crinone / funneling cervix / no cerclaige

Nea
Hello. I'm hoping someone can give me some positive feed back concerning Crinone . Sept.4 - my doctor discovered my cervix was funneling but I had length.  He put me on bed rest and restricted my work hours (from home) for five hours. I had to follow up on Wednesday- and from there he measure my cervix to be about a 2-2.5. He is sending me to a high risk doctor tomorrow to get a second opinion about the cerclaige. I'll be 21 weeks tomorrow with my baby girl. He said he usually don't do the stitch until 1.5 cm but he want a second opinion about my measurements. He also prescribed Crinone . Do anyone have any success stories? What side effects you experienced?
