I experienced this during pregnancy too 😅 My doctor said hormonal changes, increased blood flow, and lower BP during pregnancy can sometimes cause a “whooshing” sound or ringing in the ears, especially when standing up too fast.
Your BP looks a bit on the lower side too, so maybe try:
* standing up slowly
* drinking enough water
* not skipping meals
* resting more
But if it becomes very loud, constant, comes with dizziness/headache/blurred vision, or only happens on one side frequently, better mention it to your gynae just to be safe 😊
