I am not the best person to ask as I am pretty new to this lol, hug I was definitely told we cannot get constipated. My putout is like ghost at times, in fact it is today, but I don't have any pains. From Whig I have read you know when you have a blockage as output is reduced or non existent, and you habe bad pains. I think it can sort itself out, drinking lots can help, but sometimes hospital needed. You can try massaging abdomen too I think.
Do you not have an emergency contact or out of hours service? If it all gets too bad take yourself to A&E take be safe, better than ridking it. But like I say, I am not a voice of experience and am still getting used to this strange way of life myself.
