Will clitoral stimulation with a vibrator harm my baby while pregnant? Is it okay to use vibrators and or masturbate with my hand and have orgasms?

Usually not. Under most conditions self or partner sex has no effect on the developing baby. There are some health conditions where your pregnancy is unstable where the OB would put you on a low stress/bed rest like activity limitations where this might be a bad idea. When you go for visits just ask if there are any activity limitations you should follow. They will understand.
