The only reason you would need to avoid pelvic PT during pregnancy is if your OBGYN has placed you on bed rest. Otherwise, pelvic PT is a very safe and conservative way to support your pregnancy, so you don’t need specific approval from your OBGYN.
We do ask for your OB to provide a “clearance” form for internal examination and treatment. This is simply to keep everyone on the same page and ensure we work together as part of your birth team. If your OBGYN has cleared you for intercourse during pregnancy, rest assured that our internal exam or treatment is much less invasive.
