When should I call my healthcare provider while I am pregnant and in my second trimester?

Please call right away if you have:

  • Unusual or severe cramping or abdominal pain
  • Noticeable changes such as a decrease in your baby’s movement after 28 weeks’ gestation (if you don’t count six to 10 movements in one hour or less)
  • Difficulty breathing or shortness of breath that seems to be getting worse
  • Signs of premature labor including:
    • Regular tightening or pain in the lower abdomen or back
    • Any bleeding in the second or third trimester
    • Fluid leak
    • Pressure in the pelvis or vagina

Rh factor testing in the second trimester

Rh factor is an antigen protein found on most people’s red blood cells. If you don’t have the protein, then you are Rh- (negative). You will be given an injection of Rh immune globulin (called Rhogam®) during the 28th week of your pregnancy to prevent the development of antibodies that could be harmful to your baby. You will also be given an injection of Rhogam after delivery if your baby has Rh+ blood.

If you are Rh- you may also receive this injection if you: are having an invasive procedure (such as an amniocentesis), had an abdominal trauma, had any significant bleeding during pregnancy, or if your baby needs to be turned in the uterus (due to breech presentation).
