Vaginal Pressure

Anyone else experiencing vaginal pressure. Especially when standing for a period of time? I have already asked my midwife about it and she said it was normal! Also had my anatomy scan and doctor said my cervix was looking "nice and long" lol! The pressure still worries me! I've been experiencing it since about week 16 and I'm now almost 23 weeks! I think the baby is head down again though and it had eased up when the baby was breech for a week or so...
