Frequent urination is common during late stages of pregnancy. About 30 weeks onwards, the increased weight of
the growing baby and uterus start to put more pressure on the bladder causing urinary symptoms. Frequent
urination may be worse if your pelvic floor muscle is weakened due to effects of the hormone progesterone
during pregnancy, and possibly not doing enough pelvic floor exercises.
During pregnancy, the cervical opening becomes blocked with a thick plug of mucus that prevents bacteria from
entering the uterus. When the cervix begins to loosen, at the time nearing labor, the mucous plug gets
dislodged. A stringy mucous discharge tinged with pink or brown blood is a sign of impending labor. Such
"bleeding" signifies that the cervix blood vessels are rupturing as it dilates and effaces. Since
you are experiencing uterine contractions along with these symptoms, please consult a gynecologist immediately
to check whether you are nearing labour. Hope this helps you. Take care and regards!
