Yesterday afternoon I went to the movies with a friend, I was feeling fine one minute then as soon as I sat down I got the worst constipation pains ever, my friend thought I was in labour lol. Anyway it has settled down a little but I am still VERY uncomfortable to the point where I can hardly walk at times. DH suggested he go and get an enema from the chemist for me - is this safe? (I'm about 38 weeks). I've got an appointment with my Ob tomorrow but I really don't think I can wait that long, I am that uncomfortable...
