short answer yes, but you will need to go to the chemist & let them know how far along you are & they will give you some that are ok or pregnancy. I had to have them with DD because I was constipated the whole PG & even had to use one during labour before I went to the hospital. I cant remember what brand they gave me but the also gave me a liquid in a massive bottle to keep taking for the next few days afterwards to keep it moving
