I have been experiencing the same things! I have been drinking more water to help.
so far both are normal for me. Drink a big glass of juice everyday.
Totally normal,high progesterone levels slow down your bowel movement,making you constipated,wont stay that way,but as heather says drink plenty of water etc.
Very normal it's the same reason women get morning sickness all of the hormones affect your digestive system and you digest slower than you normally would. Try to eat lots of fiber rich foods (whole grains, fruits, veggies) and drink lots of water. Hope you feel better =)
