Hi mama! Maraming moms ang nakatanggap ng primrose from their OB around that time, kaya normal lang yan, your doctor probably wants to soften your cervix before labor kicks in, especially at 36 weeks na. Best thing is to follow your OB's instructions exactly and report back after the 7 days kung paano naging soft ang cervix, pero if you're nervous about anything, kahit side effects or kung paano ka nakakaramdam, don't hesitate to call your OB right away, kaya mo yan mama!
