Interstitial cystitis is a condition that causes pain in the bladder or pelvic area, and frequent urination. An intracranial hematoma occurs after a head injury and causes headache, drowsiness, confusion, and more. Valley fever is a fungal infection that starts in the lungs and causes mild flu-like symptoms.
For women having their first baby, an average first stage of labour usually lasts around 12 - 14 hours, but it can be many hours longer. This stage of labour for women having second or later babies averages about 7 hours. This is only a guide and you may find that your labour is shorter or longer than these times.
(Your due date is calculated as 40 weeks after the first day of your last menstrual period.) Labor contractions signal the beginning of childbirth. These contractions come at regular intervals, usually move from the back to the lower abdomen, last between 30-70 seconds, and get stronger and closer together over time.
