You can safely use your sex toys during pregnancy. During pregnancy, a woman’s genitalia is lubricated and engorged and as such can be ultrasensitive. Toys can enhance the sexual experience and help to get you both comfortable enough to really enjoy sex.
Whatever you do, ensure that it feels good. If you or your partner are ever uncomfortable you should stop, readjust or grab for a different toy. If you are unusually sore or in pain, or if you start bleeding you should contact your doctor.
The most important point is to be gentle especially when you just start figuring this pregnancy sex out. Remember that insertable sex toys are more rigid than a penis and with your cervix more sensitive during pregnancy you want to ensure you are being gentle.
Breasts are another sensitive area so you may want to put those nipple clamps away. Your joints will be looser so you want to be careful not to overstretch them with interesting positions or with bondage. Overstretching your joints may cause painful injuries.
