So every day when I get up have my BM shorty after waking. Well lately I haven't had to go after awaking and then go later in the day. Well For the last 2 days really I haven't had to have a BM I don't feel full like I need to have one if I try to go I will go a little but I don;t want to strain. So I don't think I am constipated as I don't feel like I need to have a BM. Is it possible that I switched to IBS-C?
