Bowels may well alter due to hormones!
10 mins B4 a bleed started I would have to dash to the loo, no arguments. Even if a period wasn't due. I always suffered severe period pains until I went on the Pill.
MayB think about what you eat during the next 5 days, make a note of everything. What you drink, snacks, main meals .......... onions, baked beans, garlic can alter how poo smells, as well as greens. [especially at this time of year ;-) ].
You may have post nasal drip. Do U get heartburn at all? which can be treated. Hormones can cause taste buds to alter, if you think of pregnancy it's often noted. Some chemotherapy the same.
