Can i have intercourse with cervical length 3 cm at 33 weeks?

check with your doc once

if its a risky pregnancy,  doctors usually mention abt the same earlier in pregnancy and you are always reminded abt the same. i am assuming if your doctor has not mentioned anything abt it as yet.. it must be safe.

but still to be on the safer side - do call ur gyno and confirm. my assumption is based on the fact that at 33 weeks also u have no info abt the same.

check with you gynaec once.
