๐ŸฉบClinical Context โ€” From a Nurse's View

Week 8 is the typical first prenatal visit week. Expect bloodwork (CBC, blood type and antibody screen, rubella titer, syphilis, hepatitis B, HIV, sometimes hemoglobinopathy screening), a urine sample, possibly a Pap if you're due, and a discussion of first-trimester genetic screening options โ€” NIPT (cell-free DNA), nuchal translucency, or both. NIPT is now offered to anyone who wants it (ACOG 2020), not just those at higher risk. If your blood type is Rh-negative, your provider will plan for RhoGAM at 28 weeks (or sooner if you bleed). The embryo is roughly the size of a raspberry and the heart rate is now 150-170 BPM โ€” surprisingly fast compared to an adult. Nausea may peak in the next 1-2 weeks before it begins easing for most people. Spotting after a transvaginal ultrasound or vaginal exam is common and not a warning. What earns a call: bleeding heavier than a period, or any one-sided pelvic pain that doesn't resolve with rest.

๐Ÿšจ When to Call (or Go to the ER)

  • !Bleeding heavier than a normal period โ€” call same day; ER if soaking pads
  • !One-sided pelvic pain that doesn't resolve in 1-2 hours โ€” ER
  • !Severe persistent vomiting with weight loss โ€” call
  • !Fever above 100.4ยฐF โ€” call
  • !Severe headache with visual changes โ€” call (early but worth flagging)

โœ… Normal โ€” Even If It Feels Worrying

  • โœ“Vivid dreams from progesterone-driven sleep changes
  • โœ“Mild cramping as the uterus stretches
  • โœ“Skin breakouts and oily hair
  • โœ“Increased clear or white discharge (leukorrhea)

โœ… To-Do This Week

  • Attend your first prenatal appointment if not done yet
  • Get bloodwork done (blood type, CBC, STI screening)
  • Start documenting your pregnancy with photos
  • Prepare for possible morning sickness remedies
  • Consider maternity clothing โ€” your body is changing
  • Rest when you can โ€” fatigue is real and valid
