Have you noticed the muscles in your uterus tightening now and then? Many women feel these random contractions — called Braxton Hicks contractions — in the second half of pregnancy. Often lasting about 30 seconds, they're irregular, and at this point, they should be infrequent and painless. Frequent contractions, on the other hand — even those that don't hurt — may be a sign of preterm labor. Call your practitioner immediately if you have more than four contractions in an hour or any other signs of preterm labor: an increase in vaginal discharge or a change in the type of discharge (if it becomes watery, mucus-like, or bloody — even if it's pink or just tinged with blood); abdominal pain or menstrual-like cramping; an increase in pressure in the pelvic area; or low back pain, especially if you didn't have it before.
Four F@#$ing Oranges!? Come on! There isn't a single piece of produce equivalent to that all by itself? I'm calling shenanigans again, Babycenter!
