just wondering if you need a prescription to get an enema? if all goes to plan i wont need one at all but i just want one sitting around at home in case i feel the need for it. last time i hadnt been to the loo for over 24 hours (cause i was induced and was in the hospital and i find it hard to go in public places TMI sorry) and i think my contractions were worse cause i was cramping up sorta from needing to go as well. anyway.. can i just get one over the counter at chemist?
