You can dry up... it is possible.
"elevated levels of progesterone potently reduce the sodium-retaining activity of aldosterone, resulting in natriuresis and a reduction in extracellular fluid volume. Progesterone withdrawal, on the other hand, is associated with a temporary increase in sodium retention (reduced natriuresis, with an increase in extracellular fluid volume"
So essentially, the wicked thirst you get during your cycle can be from high levels of P, as well as the peeing like crazy and headaches... The dip in P before AF is what causes bloating.
"Progesterone affects the vaginal epithelium and cervical mucus, making it thick and impenetrable to sperm." Or it can mean no Cm at all.. whatever it takes to prevent the sperm from making it to where it needs to go.
"If pregnancy does not occur, progesterone levels will decrease, leading, in the human, to menstruation. Normal menstrual bleeding is progesterone-withdrawal bleeding. If ovulation does not occur and the corpus luteum does not develop, levels of progesterone may be low leading to uterine bleeding." The dip in P leads to AF
"During implantation and gestation, progesterone appears to decrease the maternal immune response to allow for the acceptance of the pregnancy.Progesterone decreases contractility of the uterine smooth muscle." This means that colds and UTIs are not uncommon and can be from a coming BFP!! Also changes in bowel regularity or frequncy are also caused by P because your intestines are smooth muscle that is also affected by P.

Kinda interesting stuff when you know how hormones work. Unfortunatly, the hormones that are in our body during a regular cycle can mimic the BFP sympotoms as well
Hope that helps!!
But I definitely know too that I do get this watery cm a couple hours or up to a day before af, not this long!
to you!
I ended up not getting a BFP this month so I guess the watery cm is normal for me! I really need to start charting
