Hi, can having an orgasm after cervical stitch cause contractions, or any problems to the baby/pregnancy. 24 wks with 5 cm long cervix with stitch. ?

You will have: Occasional contractions,as long as they are not regular no problem.If your obstetrician didn't say sex was contraindicated ,no worry.

Cerclage: It appears you are asking about a cervical cerclage. In general nonpenetrative sexual activity is not restricted in women with a cerclage. Vaginal intercourse is restricted because the suture material for the cerclage is very sharp and can cause injury. Of course individual cases must be addressed by your doctor.
