I am in the same boat hun, 2 dulcolax usually work a treat for me but nothing, so I am glugging down the water today, going to have wholemeal toast for my DD food, and I have taken another dulcolax this morning as I am not going anywhere today so if I need the toilet quick its OK, official weigh in day for me tomorrow too so could really do with 'going', havent really got any advice as it would usually be dulcolax that I recommend but you have been there done that, just try upping your water and then if nothing by tonight I would try another , if you are not going anywhere in the morning that is lol x
