Perineum pain during pregnancy (34 weeks)

Hai all, its been an 8 months of my pregnancy of carrying my first child. Everything was goes well till now, but For past 1 week I’m experience a perineum pain.. its been mild to moderate. The pain usually there for every time during my usual activities. But worsen when turning while sleeping, walking especially stand up after sit for just 15-30 mnts. Does this symptom is normal at this time of pregnancy? Does anyone else experience same? I haven’t seen doctor for this issue yet. Coming 3rd May is the my appointment. Thinking of seeing dr on the day.
